Introduction to Newton’s Second Law of Motion

Newton’s Second Law of Motion is a fundamental principle in physics that helps us understand how objects move when a force is applied to them. This law, formulated by Sir Isaac Newton in the 17th century, provides a mathematical relationship between force, mass, and acceleration.

Definition of Newton’s Second Law of Motion

Newton’s Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In simpler terms, it means that the more force you apply to an object, the more it will accelerate, and the heavier the object is, the less it will accelerate for the same force.

Mathematically, this law can be expressed as:

F = m * a

Where:
– F represents the net force acting on the object, measured in Newtons (N).
– m represents the mass of the object, measured in kilograms (kg).
– a represents the acceleration of the object, measured in meters per second squared (m/s²).

Explanation of the Relationship between Force, Mass, and Acceleration

To understand the relationship between force, mass, and acceleration, let’s consider a simple example. Imagine you are pushing a shopping cart with a certain force. If you increase the force you apply, the cart will accelerate more. On the other hand, if you increase the mass of the cart, it will accelerate less for the same force.

This relationship can be further illustrated by examining the equation F = m * a. If we keep the force constant and increase the mass, the acceleration will decrease. Conversely, if we keep the mass constant and increase the force, the acceleration will increase.

For instance, if you push a small car with a force of 100 N, it will accelerate more than if you push a larger car with the same force. Similarly, if you push the same car with a force of 200 N, it will accelerate more than if you push it with 100 N.

In summary, Newton’s Second Law of Motion tells us that the acceleration of an object depends on the force applied to it and its mass. The greater the force or the smaller the mass, the greater the acceleration. Conversely, the smaller the force or the greater the mass, the smaller the acceleration.

Understanding this law is crucial in various fields, including physics, engineering, and sports. It allows us to predict and analyze the motion of objects in real-life scenarios, enabling us to design better vehicles, study the behavior of athletes, and much more. In the following sections, we will explore some practical examples of Newton’s Second Law of Motion in action.

Examples of Newton’s Second Law of Motion

Football Kicked

One example that demonstrates Newton’s Second Law of Motion is kicking a football. When a player kicks the ball, they apply a force to it. This force causes the ball to accelerate in the direction of the force applied.

The acceleration of the ball is directly proportional to the force applied and inversely proportional to the mass of the ball. In other words, the greater the force applied, the greater the acceleration of the ball. Similarly, if the mass of the ball is increased, the acceleration will decrease.

To calculate the force applied to the ball, we can use the formula F = ma, where F is the force, m is the mass of the ball, and a is the acceleration. By rearranging the formula, we can solve for force: F = ma.

Pushing the Table

Another example that illustrates Newton’s Second Law of Motion is pushing a table. When you push a table, the displacement of the table is in the direction of the applied force.

The force applied to the table causes it to accelerate in the direction of the force. The acceleration of the table depends on the force applied and the mass of the table. If a greater force is applied, the table will accelerate more. Conversely, if the mass of the table is increased, the acceleration will decrease.

Carrying Shopping Trolley

When you push or pull a shopping trolley, you are applying a force to move it. This is another example of Newton’s Second Law of Motion.

The force applied to the trolley determines its acceleration. If you push the trolley with a greater force, it will accelerate more. On the other hand, if you pull the trolley with a smaller force, it will accelerate less.

It is important to note that there is a difference between push and pull forces. When you push a trolley, the force is applied in the same direction as the motion. However, when you pull a trolley, the force is applied in the opposite direction of the motion.

Carrom Striker

In the game of carrom, when you strike the striker, it accelerates in the direction it is struck. This example also demonstrates Newton’s Second Law of Motion.

The force applied to the carrom striker determines its acceleration. If you strike the striker with a greater force, it will accelerate more. Conversely, if you strike it with a smaller force, it will accelerate less.

The distance traveled by the carrom striker is directly proportional to the force applied. In other words, the greater the force, the greater the distance traveled by the striker.

Pushing a Car

Pushing a car is another example that showcases Newton’s Second Law of Motion. When you apply a force to the car, it moves forward in the direction of the force.

The force applied to the car determines its acceleration. If you push the car with a greater force, it will accelerate more. On the other hand, if you push it with a smaller force, it will accelerate less.

The relationship between force, mass of the car, and acceleration can be described by the formula F = ma, where F is the force, m is the mass of the car, and a is the acceleration. By rearranging the formula, we can solve for acceleration: a = F/m.

Billiard Ball

When you strike a billiard ball with a cue stick, it accelerates in the direction of the force applied. This is another example of Newton’s Second Law of Motion.

The force applied to the billiard ball determines its acceleration. If you strike the ball with a greater force, it will accelerate more. Conversely, if you strike it with a smaller force, it will accelerate less.

The speed of the ball is directly proportional to the force applied. In other words, the greater the force, the greater the speed of the ball.

Hitting the Marble

When a force is incident on a marble, it displaces the marble from its position of rest. This is an example that demonstrates Newton’s Second Law of Motion.

The force applied to the marble determines the displacement it experiences. If a greater force is applied, the marble will be displaced further. Conversely, if a smaller force is applied, the displacement will be less.

In addition, when the marble is displaced, there is a transfer of kinetic energy from one marble to another. This transfer of energy is a result of the force applied.

Bowling Ball

When a force is applied to a bowling ball, it moves in the direction of the force. This is another example of Newton’s Second Law of Motion.

The force applied to the bowling ball determines its acceleration. If a greater force is applied, the ball will accelerate more. Conversely, if a smaller force is applied, the acceleration will be less.

The relationship between force and acceleration can be described by the formula F = ma, where F is the force, m is the mass of the bowling ball, and a is the acceleration. By rearranging the formula, we can solve for force: F = ma.

These examples demonstrate how Newton’s Second Law of Motion applies to various real-life scenarios. By understanding this law, we can better comprehend the relationship between force, mass, and acceleration in the world around us.

Pulling a Trolley Suitcase

When it comes to understanding Newton’s second law of motion, it’s helpful to explore real-life examples that demonstrate how force, mass, and acceleration are interconnected. One such example is pulling a trolley suitcase. Let’s take a closer look at how this scenario exemplifies the principles of Newton’s second law.

Description of the Example

Imagine you’re at the airport, and you need to pull your trolley suitcase from the check-in counter to the boarding gate. The trolley suitcase is equipped with wheels, making it easier to transport. However, you still need to exert a force to set it in motion and keep it moving.

Explanation of How a Force is Applied to Pull the Trolley Forward

To pull the trolley suitcase forward, you apply a force in the direction you want it to move. This force is typically exerted by gripping the handle of the suitcase and pulling it towards you. As you pull, the force you apply is transmitted to the wheels, causing them to rotate. The rotation of the wheels propels the trolley suitcase forward.

Discussion of the Relationship Between Force, Mass of the Trolley, and Acceleration

According to Newton’s second law of motion, the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. In the case of the trolley suitcase, the force you apply determines its acceleration. The greater the force, the faster the trolley will accelerate.

On the other hand, the mass of the trolley suitcase affects its acceleration inversely. If the trolley suitcase is heavier, it will require a greater force to achieve the same acceleration as a lighter suitcase.

In practical terms, this means that if you want to increase the acceleration of the trolley suitcase, you need to apply a greater force. Similarly, if you want to slow down or stop the trolley, you need to apply a force in the opposite direction.

Understanding how force, mass, and acceleration are related in the context of pulling a trolley suitcase helps illustrate the principles of Newton’s second law of motion. By applying this law, we can better comprehend the physics behind everyday actions and objects.

Sliding Window

Description of the Example

Imagine you are trying to slide open a stubborn window. You push against it with all your might, but it doesn’t budge. This everyday scenario can be explained using Newton’s second law of motion.

Explanation of How a Force is Applied to Slide a Window Open

Newton’s second law of motion states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. In the case of sliding a window open, you are applying a force to overcome the friction between the window and its frame.

When you push on the window, you are exerting a force in a specific direction. According to Newton’s second law, this force will cause the window to accelerate in the same direction. However, the window’s mass resists this acceleration, making it harder to slide open.

Discussion of the Relationship Between Force and Acceleration of the Window

The relationship between force and acceleration can be understood through the equation F = ma, where F represents force, m represents mass, and a represents acceleration. In the case of sliding a window open, the force you apply is directly related to the acceleration of the window.

If you increase the force you exert on the window, the acceleration of the window will also increase. This means that the window will slide open faster. Conversely, if you decrease the force, the acceleration and sliding speed of the window will decrease as well.

Explanation of How a Force is Applied to Lift a Stack of Books

Another example that demonstrates Newton’s second law of motion is lifting a stack of books. When you lift a stack of books off the ground, you are applying a force to overcome the gravitational pull on the books.

Discussion of the Relationship Between Force, Mass of the Books, and Acceleration

Similar to the sliding window example, the relationship between force, mass, and acceleration applies here as well. The force you exert to lift the stack of books is directly related to the acceleration of the books.

If you increase the force, the acceleration of the books will increase, causing them to lift off the ground more quickly. On the other hand, if you decrease the force, the acceleration and lifting speed of the books will decrease.

It’s important to note that in both examples, the mass of the object being moved affects the acceleration. The greater the mass, the more force is required to achieve the same acceleration.

In conclusion, Newton’s second law of motion provides a fundamental understanding of how forces and masses interact to produce acceleration. Whether it’s sliding a window open or lifting a stack of books, this law helps explain the relationship between force, mass, and acceleration in various real-life scenarios.

Dashing on a Boat

Description of the example

Imagine yourself on a boat, gliding through the calm waters of a lake on a sunny day. As you stand at the bow, you notice that the boat starts moving forward when you push against the railing. This simple action exemplifies Newton’s second law of motion.

Explanation of how a force applied to a boat causes it to move forward

When you push against the railing of the boat, you apply a force in the opposite direction. According to Newton’s second law of motion, the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. In this case, the boat’s mass remains constant, so the force you apply causes the boat to accelerate forward.

Discussion of the relationship between force, acceleration, and direction of motion

The direction of motion of the boat is determined by the direction of the force applied. In this example, when you push against the railing, the force is directed backward. However, according to Newton’s third law of motion, for every action, there is an equal and opposite reaction. Therefore, the boat moves forward in response to the backward force you exerted on the railing.

Explanation of how the gravitational force causes a fruit to fall downward

Let’s consider another example to understand Newton’s second law of motion. Imagine you are standing under a tree, and you pluck a ripe fruit from its branch. As soon as you detach the fruit, it falls straight down towards the ground.

This downward motion of the fruit is due to the force of gravity acting upon it. Gravity is a force that attracts objects towards each other. In this case, the Earth‘s gravitational force pulls the fruit downward, causing it to accelerate towards the ground.

Explanation of how a force is applied to roll a hula hoop on a surface

Now, let’s explore the motion of a hula hoop rolling on a surface. When you apply a force by pushing the hula hoop, it starts rolling forward. This motion can be explained using Newton’s second law of motion.

The force you apply to the hula hoop causes it to accelerate forward. The acceleration depends on the force applied and the mass of the hula hoop. The lighter the hula hoop, the easier it is to accelerate.

Discussion of the relationship between force, acceleration of the hoop, and direction of motion

The direction of motion of the hula hoop is determined by the direction of the force applied. When you push the hula hoop forward, the force is directed in the same direction. As a result, the hula hoop accelerates in the forward direction.

The acceleration of the hula hoop depends on the force applied and the mass of the hoop. The greater the force applied or the lighter the hula hoop, the greater the acceleration.

Explanation of how a force is applied to set a swing in motion

Have you ever enjoyed swinging in a playground? The motion of a swing can be explained using Newton’s second law of motion. When you push the swing, it moves forward and backward.

By applying a force to the swing, you cause it to accelerate in the direction of the force. The swing moves forward due to the force you exerted. As it reaches the highest point, the force decreases, causing the swing to decelerate and eventually reverse its direction.

Explanation of how a force is applied to blow out a candle

Blowing out a candle is a simple action that demonstrates Newton’s second law of motion. When you blow air towards the candle flame, it extinguishes.

The force you apply to blow air causes the air molecules to accelerate in the direction of the candle flame. As the air molecules collide with the flame, they disrupt the combustion process, leading to the extinguishing of the flame.

Discussion of the relationship between force, acceleration of air molecules, and extinguishing the flame

The force applied to blow air determines the acceleration of the air molecules. The greater the force, the higher the acceleration of the air molecules. When the accelerated air molecules collide with the flame, they disturb the balance of heat and oxygen required for combustion, resulting in the flame being extinguished.

Explanation of how a boomerang returns to the thrower

The boomerang is a fascinating example of Newton’s second law of motion. When thrown correctly, a boomerang not only travels in a curved path but also returns to the thrower.

When you throw a boomerang, you apply a force by giving it a spin. This spin creates an imbalance in the forces acting on the boomerang, causing it to accelerate and follow a curved path. The shape and design of the boomerang, along with the spin, generate lift and create an aerodynamic effect, allowing it to return to the thrower.

Discussion of the relationship between force, distance traveled, and acceleration

The force applied to the boomerang determines its acceleration. The greater the force, the higher the acceleration, which affects the distance traveled by the boomerang. Additionally, the design and shape of the boomerang play a crucial role in generating lift and allowing it to return to the thrower.

Explanation of how a force is applied to throw a dart

Throwing a dart is a classic example of Newton’s second law of motion. When you throw a dart, you apply a force by pushing it forward.

The force you apply to the dart causes it to accelerate in the direction of the throw. The acceleration depends on the force applied and the mass of the dart. The lighter the dart, the easier it is to accelerate, resulting in a faster throw.

Discussion of the relationship between force, acceleration of the dart, and direction of motion

The direction of motion of the dart is determined by the direction of the force applied. When you throw the dart forward, the force is directed in the same direction. As a result, the dart accelerates in the forward direction.

The acceleration of the dart depends on the force applied and the mass of the dart. The greater the force applied or the lighter the dart, the greater the acceleration, leading to a faster throw.

Frequently Asked Questions

How to calculate the force required to move an object with a given mass and acceleration?

When it comes to calculating the force required to move an object, Newton’s second law of motion comes into play. According to this law, the force acting on an object is directly proportional to its mass and acceleration. In other words, the force required to move an object is equal to the product of its mass and acceleration.

To calculate the force, you can use the formula:

Force = Mass x Acceleration

Let’s say you have an object with a mass of 5 kilograms and an acceleration of 10 meters per second squared. By plugging these values into the formula, you can calculate the force required to move the object:

Force = 5 kg x 10 m/s^2 = 50 Newtons

Therefore, the force required to move the object is 50 Newtons.

How to determine the net acceleration of an object under the influence of multiple forces?

When an object is under the influence of multiple forces, the net acceleration can be determined by considering the vector sum of all the forces acting on the object. The net acceleration is the overall acceleration experienced by the object due to the combined effect of all the forces.

To determine the net acceleration, follow these steps:

1. Identify all the forces acting on the object.
2. Determine the direction and magnitude of each force.
3. Add up all the forces vectorially, taking into account their direction.
4. Divide the resultant force by the mass of the object to obtain the net acceleration.

For example, let’s say an object is experiencing two forces: a force of 20 Newtons to the right and a force of 10 Newtons to the left. The mass of the object is 2 kilograms. To find the net acceleration:

1. The force to the right is +20 N, and the force to the left is -10 N.
2. Adding these forces vectorially, we get a resultant force of +10 N to the right.
3. Dividing the resultant force by the mass of the object (2 kg), we find the net acceleration:

Net Acceleration = Resultant Force / Mass = 10 N / 2 kg = 5 m/s^2

Therefore, the net acceleration of the object is 5 meters per second squared.

Why do moving objects eventually come to rest?

According to Newton’s second law of motion, an object will continue to move at a constant velocity unless acted upon by an external force. This concept is known as inertia. Inertia is the tendency of an object to resist changes in its state of motion.

When a moving object comes into contact with a surface or encounters friction, it experiences a force that opposes its motion. This force is known as frictional force. Frictional force acts in the opposite direction to the object’s motion, gradually slowing it down.

As the object slows down, the force of friction increases until it becomes equal in magnitude to the force propelling the object forward. At this point, the net force acting on the object becomes zero, resulting in the object coming to rest.

Explanation of the factors contributing to an object’s equilibrium state of rest

An object is said to be in a state of equilibrium when the net force acting on it is zero. In other words, the object is either at rest or moving at a constant velocity. There are two main factors that contribute to an object’s equilibrium state of rest:

1. Balanced Forces: When the forces acting on an object are balanced, the net force is zero. This means that the forces are equal in magnitude and opposite in direction, canceling each other out. As a result, the object remains at rest.

2. Friction: Friction plays a crucial role in maintaining an object’s equilibrium state of rest. When an object is on a surface, the force of friction opposes the object’s tendency to move. The frictional force acts in the opposite direction to the applied force, preventing the object from sliding or moving.

For example, imagine a book placed on a table. The weight of the book is balanced by the normal force exerted by the table, resulting in a net force of zero. Additionally, the frictional force between the book and the table prevents it from sliding off.

In summary, an object’s equilibrium state of rest is achieved when the forces acting on it are balanced and when friction opposes its motion. These factors work together to keep the object at rest.

The lever of the nail cutter is held at 45 degrees when opened which is constrained by the motion of the two blade joints by the pin.

The other blades which are called filed can be moved only from one side and at a 180-degree angle. All the parts of the nail cutter are restricted to work in a given range of motion.

Car Trunk

A door of a trunk of a car can be moved to a certain angle up to 90 degrees. A trunk of a car is used to store luggage. Even the doors of a car are an example of a range of motion as the doors can be opened up to a certain limit.

Metronome

It is a device used to listen to a beat by the musician by adjusting the speed of oscillation of the device and catching the rhythm.

The speed of the metronome is adjusted by moving a weight over the pendulum stick, and it oscillated to the given range of frequency. The range of motion of the oscillator of a metronome is limited by the adjusted oscillation of the pendulum.

Hands and Legs

The motion of hands and legs is limited by the joints. We are able to move our hands at a 180-degree angle from the front but the same is not true while moving backward. The legs can be moved to more than 180 degrees but we cannot move our legs at a 360-degree angle.

Walking

While walking the motion of the legs is a repetitive motion and occurs and a fixed angle of motion.

The legs are bending at a small angle while lifting the leg and kept forward. The range of motion of the leg is limited by every joint of the leg helping while walking.

Fingers

We are able to bend our fingers from knuckles to every phalange of a finger to a certain angle in a forward direction. The range of motion of our fingers is limited by the joints. We are unable to bend our fingers backward, which specifies the range of motion of the fingers.

Tap

There are different tap handles used for different valves that adjust the pressure of the water. Some rotating tap handles can be rotated at 90 degrees, of some can be rotated from 0-360 degrees too.

But the range of motion of the handle is fixed at a constant angle of rotation.

Satellites

The geostationary satellites are mounted above the surface of the Earth about 36 thousand kilometers and the speed of the satellite is synchronized with the speed of the Earth. The range of motion of the satellites is maintained by the gravitational pull of the Earth so that they cannot escape away from the Earth.

Spectacle

The small sticks-like structure of the spectacle which is worn around the ears to hold the specs are called the temples of the spectacle and is moved between 0-90 degree angles.

Photo Frame

A small easel is there to support the photo frame to stand on the plane surface like a table, showcase, etc. This easel can be moved to a small range.

Swings

The swings oscillate at an angle up to which it was raised and released back, gradually decreasing its angle of oscillation.

Frequently Asked Questions

Does the range of motion measure by the angle of motion?

The range of motion comes into the picture when the motion of an object is constrained at some limit.

This range of motion of an object can be measured by an angle because the object is able to move at a certain angle may be in any direction.

Why does the range of motion constrain?

Some objects cannot be moved beyond a certain range.

These objects are joint or restrained to move because they are connected with some other object that constrains their motion.

The motion of the object is said to be rolling if the rotating object is in a translation motion at the same time.

The rolling motion comes in the scenario is the surface of the object possessing rotational motion comes in a contact with the other surface. Let us discuss some of the rolling motion examples as listed here below:-

Paint Roller

A paint roller is dipped into the paint and rolled on the wall back and forth to apply the color to the wall.

This motion of the paint roller on the wall is a rolling motion. Dipping half of the roller in the paint instead of fully helps in evenly spreading the paint on the cover.

Ball

Since the ball is round in shape it rolls on the ground when the force is applied to displace it from the initial position. The ball will rotate at an axis perpendicular to the direction of the force applied.

Bicycle

The bicycle is an example of multiple motions too. The tires of the bicycle rotate at a fixed axis while the bicycle moves in a linear motion forward due to the rotational motion of the tires.

The distance covered by one rotation of the tires is equal to the length of the circumference of the tire.

Cylinder

The cylindrical surface area is circular in shape and hence upon rolling the cylinder on the surface it will roll traveling to a certain distance.

Bottles

A bottle fallen on the ground will roll on the surface due to the effect of the applied force or air resistance.

The air resistive force depends upon the volume of the liquid present in the container and the density of a liquid.

Hula Hoop

The hula hoop is a circular ring in shape that you put around the body and gives it torque. On keeping the hula hoop on the plane surface it will roll on the surface.

Marbles

The marbles are round in shape. On hitting the marble on a group of marbles, the marbles start rolling depending upon the impact that each marble exerts.

Billiard Ball

The billiard ball will roll on the board after hitting it with the stick.

As the player applies a force on the ball, the billiard ball will gain kinetic energy along with the momentum and accelerate towards the target. Upon colliding with another ball in the path, the momentum of the ball is transferred to the ball.

Chapati Roller

A roller is used to make a chapatti. A roller is kept on the dough and the roller spreads the dough evenly to make a chapatti.

The dough is spread based on the pressure incident on the dough by the roller and the force applied to the roller.

Boulder Falling from the Hill

A boulder rolling down from the high hills is also an example of the rolling motion. You must have observed the big boulder standing on the rock click even at a pointed edge of the boulder. If the force relevant to the mass of the boulder is incident on the bounder then it will accelerate rolling down the hill till the equivalent resistive force is exerted on the hill.

Bowling Ball

Upon throwing the bowling ball, it will roll towards the bowling pin. The rectilinear path of the ball depends upon the point of gravity of the bowling ball and its moment of inertia and the force applied to the ball while making a throw.

Round Cutter

A round cutter composes of a circular blade with different shapes connected with a lever holder with a screw such that the blade is free to rotate. It is used to cut the sides of roti, pizza, naan, etc. into pieces and give different shapes.

This is achieved by rolling the cutter over the naan. The cutter moves in a rotational as well as the linear motion rolling over the naan.

Wheels of Car

A car in acceleration moves in a linear motion due to the rolling motion of the tires. The rolling motion of the tires determines the speed of acceleration of the car. One rotation of the tire covers a distance equal to its circumference.

The Fruit Fell on the Ground

On detaching a fruit from the tree, the gravitation potential energy of the fruit will convert into kinetic energy and it will fall down on the ground and bounce back because of the presence of the potential energy. It then rolls for a short distance it the entire energy stored in the fruit is nullified.

Gym Ball

A gym ball is used to do the balancing exercise. Due to its round shape, it can easily be rolled on applying little force to it.

Spreading a Carpet

If you take a roll of a carpet and spread it, the carpet will roll out opening each concentric roll of a carpet on each rotation. As the size of the concentric circle made out of carpet keeps on reducing thus the speed of the spreading carpet on the floor appears to be increased after every rollout.

Road Roller

Rollers are cylindrical in shape that is used to level and compact soil, concrete to construct the metallic road, and in landfills by rolling it over the heap of mass.

Due to its cylindrical shape mechanical structure, it compresses the soil and concrete even making the roads tough and strong increasing the density of the construction.

Rolling Down from the Slope

Any object rolling down from a slope possesses the rolling motion. The speed of the object rolling down increases with a slope depending upon the configuration of the object.

Children Playing with Tire

A child keeps the tire in the momentum by applying torque over it to increase the angular velocity of the tire. If the momentum is lost then the tire will fall down. The tire in its motion is an example of the rolling motion. The tire is rolling on the road.

Skating

The skater has wheels underneath the shoes that help is the motion.

The wheels are in the rolling motion to accelerate the body over it.

Frequently Asked Questions

Does any round-shaped object possess the rolling motion?

It is obvious that any round object will rotate and roll easily.

Depending upon the force applied to the mass of the object the round-shaped object is set into motion. If the surface of the object in motion comes in contact with the plane surface it will move with the rolling motion.

Does the rolling motion of the object depend upon the type of surface it is rolling on?

The rolling motion of the object depends upon the smoothness of the surface.

The rolling motion of the object may resist due to the roughness of the surface, while on the plane surface the object will easily roll.

Reciprocating motion is a type of back-and-forth movement that is commonly observed in various aspects of our daily lives. From the simple motion of a pendulum to the complex mechanisms of engines and machines, reciprocating motion plays a significant role in many applications. In this section, we will explore the definition of reciprocating motion, how it differs from other types of motion, and why understanding it is important in our everyday lives.

Definition of Reciprocating Motion

Reciprocating motion can be defined as a repetitive back-and-forth movement along a straight line. It involves an object or a part of a machine moving in one direction and then returning to its original position in the opposite direction. This motion can be linear or rotational, depending on the application.

To better understand reciprocating motion, let’s consider a simple example: the motion of a piston in an engine. As the piston moves up and down within the cylinder, it follows a reciprocating motion pattern. This motion is crucial for the engine to convert the linear motion of the piston into rotational motion, ultimately powering the vehicle or machine.

Explanation of How Reciprocating Motion Differs from Other Types of Motion

Reciprocating motion differs from other types of motion, such as oscillatory or continuous motion, in several ways. While oscillatory motion involves repetitive movement around a fixed point, reciprocating motion involves movement along a straight line. On the other hand, continuous motion refers to a smooth and uninterrupted flow without any back-and-forth movement.

One key characteristic of reciprocating motion is its periodic nature. The object or part undergoing reciprocating motion follows a repetitive pattern, moving back and forth within a specific range. This pattern can be regular, with equal intervals between each cycle, or irregular, with varying intervals.

Importance of Understanding Reciprocating Motion in Daily Life

Understanding reciprocating motion is essential in various aspects of our daily lives. Whether it’s the functioning of machines, the mechanics of our bodies, or the natural phenomena we encounter, reciprocating motion is at play.

In machines and engines, reciprocating motion is utilized to convert linear motion into rotational motion. This is crucial in applications such as internal combustion engines, where the reciprocating motion of pistons drives the crankshaft, generating power and enabling the movement of vehicles.

Reciprocating motion is also observed in our bodies. For instance, the pumping action of the heart involves the reciprocating motion of the heart muscles, allowing blood to circulate throughout the body. Similarly, the motion of our limbs, such as walking or waving, involves reciprocating motion.

Furthermore, reciprocating motion can be found in various natural phenomena. The swinging of a pendulum, the movement of ocean waves, and the fluttering of bird wings are all examples of reciprocating motion in nature.

Examples of Reciprocating Motion in Daily Life

Reciprocating motion is a type of back-and-forth movement that can be observed in various everyday objects and machines. Let’s explore some interesting examples of reciprocating motion in our daily lives.

Motion of a Needle in a Sewing Machine

One common example of reciprocating motion is seen in the needle of a sewing machine. As you sew, the needle moves up and down rapidly, creating a stitch in the fabric. This back-and-forth motion is achieved through a mechanism that converts rotary motion into reciprocating motion. The needle is attached to a reciprocating arm, which is driven by a rotating shaft. This mechanism allows for precise and efficient stitching, making sewing machines indispensable tools for tailors, seamstresses, and hobbyists alike.

Door Bell Ringer

Have you ever wondered how a doorbell works? Well, the doorbell ringer is another example of reciprocating motion. When you press the doorbell button, it triggers a mechanism that causes a small hammer to move back and forth rapidly, striking a metal plate or bell. This back-and-forth motion produces the familiar ringing sound that alerts you to someone’s presence at the door. The reciprocating motion in a doorbell is typically achieved using an electromagnet, which attracts and releases the hammer in a rhythmic pattern.

Reciprocating Pumps

Reciprocating pumps are commonly used in various industries, including oil and gas, chemical, and agriculture. These pumps are designed to move fluids by using a piston or plunger that moves back and forth within a cylinder. As the piston moves in one direction, it creates a vacuum that draws in the fluid. When the piston moves in the opposite direction, it compresses the fluid and forces it out through a discharge valve. Reciprocating pumps are known for their high pressure and flow rates, making them ideal for applications that require precise control and high efficiency.

Reciprocating Engines

Reciprocating engines, also known as piston engines, are widely used in automobiles, motorcycles, and small aircraft. These engines convert the reciprocating motion of pistons into rotational motion, which drives the wheels or propellers. The pistons move up and down within cylinders, drawing in a fuel-air mixture and igniting it to produce power. The reciprocating motion of the pistons is converted into rotary motion through a crankshaft, which is connected to the pistons via connecting rods. Reciprocating engines are known for their reliability, efficiency, and versatility, making them the preferred choice for many transportation applications.

Power Hacksaw Machine

In metalworking, a power hacksaw machine is commonly used to cut through metal bars, pipes, and other solid materials. This machine utilizes a reciprocating motion to move the saw blade back and forth, allowing it to make precise and efficient cuts. The reciprocating motion is achieved through a mechanism that converts rotary motion into linear motion. As the saw blade moves back and forth, it gradually cuts through the material, making it an essential tool in industries such as fabrication, construction, and manufacturing.

Shaper Machine

A shaper machine is a machining tool used to shape and contour metal workpieces. It employs a reciprocating motion to remove material and create flat surfaces, grooves, and profiles. The reciprocating motion is achieved through a mechanism that converts rotary motion into linear motion. As the cutting tool moves back and forth, it gradually removes material from the workpiece, resulting in the desired shape. Shaper machines are commonly used in workshops and manufacturing facilities for precision machining operations.

Movement in Loudspeaker Coil

When you listen to music or watch a movie, the sound is produced by a loudspeaker. The movement of the loudspeaker coil is an example of reciprocating motion. Inside a loudspeaker, an electrical signal is converted into sound by a diaphragm attached to a coil. As the electrical current passes through the coil, it creates a magnetic field that interacts with a permanent magnet. This interaction causes the coil to move back and forth rapidly, pushing and pulling the diaphragm. The diaphragm, in turn, creates sound waves that we perceive as sound.

Expansion of the Burning Fuel in Cylinders

In internal combustion engines, such as those found in cars and motorcycles, the expansion of burning fuel is a crucial part of the reciprocating motion. When the fuel-air mixture is ignited inside the cylinders, it rapidly expands, pushing the piston downward. This downward motion is the power stroke, which generates the rotational force needed to propel the vehicle. The reciprocating motion of the piston is then converted into rotary motion through a crankshaft, as mentioned earlier. This process repeats in a continuous cycle, providing the necessary power to drive the vehicle.

These examples highlight the diverse applications of reciprocating motion in our daily lives. From sewing machines to engines, reciprocating motion plays a vital role in various devices and mechanisms. Understanding the principles behind reciprocating motion can deepen our appreciation for the engineering marvels that surround us.

Hand Operated Well Pump

A hand-operated well pump is a prime example of reciprocating motion in everyday life. It is a simple yet effective device used to extract water from wells without the need for electricity or fuel. This type of pump relies on the reciprocating motion of a lever or handle to draw water from underground sources.

How Does It Work?

The hand-operated well pump consists of several key components that work together to create the reciprocating motion needed to pump water. These components include:

1. Cylinder: The cylinder is a hollow tube that is submerged in the well. It is responsible for housing the piston and allowing water to enter and exit the pump.

2. Piston: The piston is a cylindrical object that fits snugly inside the cylinder. It is connected to a rod or lever, which is operated by hand. When the lever is moved up and down, the reciprocating motion of the piston creates pressure changes within the cylinder, allowing water to be drawn in and pushed out.

3. Valves: The pump also contains valves that control the flow of water. There are typically two valves – one at the bottom of the cylinder, known as the foot valve, and one at the top, known as the delivery valve. These valves open and close in response to the reciprocating motion of the piston, ensuring that water flows in the desired direction.

Advantages of Hand Operated Well Pumps

Hand-operated well pumps offer several advantages over other types of pumps, making them a popular choice in areas with limited access to electricity or fuel. Some of these advantages include:

1. Reliability: Since hand-operated well pumps do not rely on external power sources, they can be used in remote locations or during power outages. This makes them a reliable option for accessing water when other methods may not be available.

2. Cost-Effective: Hand-operated well pumps are relatively inexpensive compared to electric or fuel-powered pumps. They require minimal maintenance and have a long lifespan, making them a cost-effective solution for water extraction.

3. Portability: Hand-operated well pumps are lightweight and portable, making them easy to transport and install. This makes them ideal for temporary setups or situations where mobility is required.

4. Environmental Friendly: Hand-operated well pumps do not contribute to carbon emissions or pollution. They operate using human power, making them an environmentally friendly choice for water extraction.

Applications of Hand Operated Well Pumps

Hand-operated well pumps have a wide range of applications, especially in areas where access to clean water is limited. Some common applications include:

• Rural Communities: Hand-operated well pumps are commonly used in rural communities where electricity or fuel-powered pumps are not readily available. They provide a reliable and cost-effective solution for accessing clean water.

• Emergency Situations: Hand-operated well pumps are often used in emergency situations such as natural disasters or humanitarian crises. They can quickly provide access to water when infrastructure is damaged or unavailable.

• Off-Grid Living: Hand-operated well pumps are popular among individuals or communities living off the grid. They offer a sustainable and independent water source without the need for external power.

• Sustainable Farming: Hand-operated well pumps can be used in small-scale farming operations to irrigate crops or provide water for livestock. They offer a low-cost and environmentally friendly solution for agricultural water needs.

Detailed Explanation of Reciprocating Motion Examples

Reciprocating motion is a back-and-forth movement that is commonly found in various machines and devices. In this section, we will explore some interesting examples of reciprocating motion and how it is applied in different contexts.

Motion of a Needle in a Sewing Machine

One of the most familiar examples of reciprocating motion is the motion of a needle in a sewing machine. When you operate a sewing machine, the needle moves up and down rapidly, creating stitches as it passes through the fabric. This back-and-forth motion of the needle is achieved through a reciprocating mechanism within the machine.

The reciprocating motion of the needle allows it to puncture the fabric and create a loop of thread, which is then interlocked with another thread to form a stitch. This continuous up-and-down motion of the needle enables the sewing machine to stitch fabric quickly and efficiently.

Door Bell Ringer

Another everyday example of reciprocating motion is the doorbell ringer. When someone presses the doorbell button, it sets off a mechanism that generates a reciprocating motion. This motion causes a small hammer to strike against a metal plate, producing a sound that alerts the occupants of the house.

The reciprocating motion in a doorbell ringer is created by an electromagnet. When the doorbell button is pressed, an electrical current flows through the electromagnet, causing it to attract and release the hammer in a rapid back-and-forth motion. This motion produces the characteristic ringing sound that we associate with doorbells.

Reciprocating Pumps

Reciprocating pumps are commonly used in various industries to move fluids such as water, oil, or gas. These pumps work by converting rotary motion into reciprocating motion, which creates the necessary pressure to move the fluid.

In a reciprocating pump, a piston or plunger moves back and forth within a cylinder. As the piston moves away from the cylinder, it creates a vacuum, drawing in the fluid. When the piston moves back towards the cylinder, it compresses the fluid, forcing it out through a discharge valve. This reciprocating motion allows the pump to move the fluid in a controlled and efficient manner.

Reciprocating Engines

Reciprocating engines, also known as piston engines, are widely used in automobiles, aircraft, and other machinery. These engines convert reciprocating motion into rotary motion, which is then used to drive the wheels or propellers.

In a reciprocating engine, the piston moves up and down within a cylinder, driven by the combustion of fuel. As the fuel-air mixture ignites, it expands rapidly, pushing the piston downward. This downward motion is converted into rotary motion through a crankshaft, which ultimately drives the wheels or propellers. The reciprocating motion of the piston is crucial for the engine to generate power and propel the vehicle or machine.

Power Hacksaw Machine

A power hacksaw machine is a cutting tool that uses reciprocating motion to cut through metal or other materials. This machine consists of a saw blade that moves back and forth in a horizontal direction, cutting the material as it moves.

When the power hacksaw machine is turned on, an electric motor drives the saw blade in a reciprocating motion. As the blade moves forward, it cuts into the material, and as it moves backward, it retracts, ready for the next cutting stroke. This reciprocating motion allows the power hacksaw machine to make precise and efficient cuts in various materials.

Shaper Machine

A shaper machine is another example of a machine that utilizes reciprocating motion for cutting and shaping metal or other materials. This machine consists of a cutting tool called a single-point cutting tool, which moves back and forth in a linear motion.

When the shaper machine is in operation, the cutting tool is attached to a ram that moves in a reciprocating motion. As the ram moves forward, the cutting tool removes material from the workpiece, creating the desired shape or profile. The reciprocating motion of the cutting tool allows for precise and controlled shaping of the material.

Movement in Loudspeaker Coil

In a loudspeaker, the movement of the coil is an example of reciprocating motion. When an electrical current is passed through the coil, it creates a magnetic field. This magnetic field interacts with a permanent magnet, causing the coil to move back and forth.

The reciprocating motion of the coil is responsible for producing sound waves. As the coil moves, it pushes and pulls on a diaphragm, which in turn creates variations in air pressure, producing sound. This reciprocating motion allows loudspeakers to produce the audio we hear in various devices, such as radios, televisions, and music systems.

Expansion of the Burning Fuel in Cylinders

In internal combustion engines, such as those found in cars, reciprocating motion is crucial for the combustion process. When fuel is ignited in the cylinders of an engine, it rapidly expands, creating a high-pressure environment.

This expansion of the burning fuel forces the piston to move downward in a reciprocating motion. As the piston moves, it transfers the energy generated by the combustion process to the crankshaft, which ultimately drives the wheels of the vehicle. The reciprocating motion of the piston is essential for converting the energy from the burning fuel into useful work.

The relative motion is a motion of an object with respect to another frame of reference.

Suppose the object is moving at velocity v₁ and another object is moving away from that object with velocity v₂, then the relative velocity of both the object in their frame of reference will be the addition of both the velocities. Here is a list of relative motion examples:-

The Passenger in a Bus

The passenger standing in a bus in a stationary position but the relative motion of the passengers in a bus is equal to the velocity of the bus.

The passengers are moving along with the bus with the displacement equal to the rate of displacement of the bus.

A Person walking in a Train in a Forward Direction

The speed of a person walking in a train is relative to the speed of the moving train. The walking speed of the person would be a, but in another frame of reference for the observer standing outside the train the speed of the person is relative to the train. Since the person is moving forward direction with the moving train velocity b then the relative velocity of the man is a+b.

The Table moved with a Stack of Books on It

The stack of books is at rest, hence the velocity of the book with the reference point on the table is zero. But for viewers, the velocity of the books is relative to the speed of the table.

Passengers on the Roller Coaster

The passenger sitting on a roller coaster will see that the other passengers are stationary and not moving in his frame of reference.

The relative motion of the passenger with the frame of reference of another passenger is zero. But the actual speed of the passenger is relative to the speed of the roller coaster.

The Vehicle Close by Moved in the Backward Direction

You must have noticed sitting in a vehicle if another vehicle standing stationary moves ahead then as per your frame of reference you feel that the vehicle in which you are sitting is taken backward. If the same vehicle is taken in the backward direction, it appears as if your vehicle is moved forward and vice versa.

A Boat Floating on Water

A boat floating on the water appears to be stationary with the frame of reference of the ocean waves.

For a person standing in a boat in open water, it appears to him that the boat is stationary because his relative speed matches the speed of the boat.

Marching

For a person marching in a group, the speed of the other marchers in a group in his frame of reference is zero because all the members are moving at the same speed and hence appear stationary.

Two Friends Walking Together

If the two friends are walking together at the same speed then the relative velocity of both with respect to each other will be zero.

Another person watching them from a far distance will see the positive velocity of both the friends.

Clock in the Bus

A clock in the bus is moving with the relative speed of the bus. A clock is actually stationary fixed at one point. For any point of reference from the bus, the velocity of a clock is zero, but for a point of reference outside the bus, the velocity of a clock is relative to the velocity of the bus.

Bicyclist Riding in the Rain

If the bicyclist riding a cycle in a rain at a certain velocity, he will notice that the speed of the rain is more than the actual speed of the raindrops. For his point of reference, the relative velocity of the raindrop is the velocity of the raindrop plus his velocity hence he feels that the speed of the rain is more than the actual.

Skiing

The relative velocity of the skiboard in the reference point of the skier is zero because he is standing on the board which is moving along with him.

Well for another reference point the relative velocity of the skier is relative to the board.

Geostationary Satellite

The geostationary satellites are those mounted 36,000 km above the surface of the Earth and the speed of the satellite is in sync with the speed of the Earth. Hence, the speed of the geostationary satellite from the reference point of the earth and the satellite appears to be zero.

Kayaking

The relative speed of the kayak depends upon the speed of the water current. If the kayak moves in the direction of the current then the relative speed of the kayak will be the addition of the speed of water flow and the kayak, in contrary, if the kayak is traveling in the direction opposite to the flow of water then the relative speed of kayak will reduce.

Swimming

If the ocean waves are approaching the swimmer, the relative velocity of the swimmer will be lower than his actual velocity.

For a swimmer, it will appear that he is moving faster but the speed of the waves decreases the velocity of the swimmer.

Riding in Helicopter

The relative motion of a person sitting in a helicopter is equal to the speed of the helicopter because the person is in a stationary position.

Sitting on a Swing

The speed of a girl sitting on a swing is in relative motion with the oscillating swing.

A girl is sitting stationary on the swing and her actual velocity is zero. But since she is in motion along with the swing, her relative velocity is equal to the velocity of a swing.

A Ball Passed to the Player Approaching Towards Him

For the player who is passing the ball, the velocity of a ball will be the actual velocity, but for a catcher who is approaching the ball, for him, the velocity will be more than the actual. The relative velocity in his point of reference is the addition of the velocity of a ball and his running speed towards the ball.

A Vehicle Crossing a Bicycle Rider and a Car

For a car driver, the relative velocity of a vehicle will be more compared to the relative velocity with respect to the bicyclist. This is because the speed of a car is more than the bicycle. For two objects appearing towards each other, the velocities add up.

Mobile Kept in a Pocket while Walking

The relative velocity of mobile is equal to the walking speed. Mobile in a pocket is stationary with a reference point of a carrier.

Object Released from the Moving Car

Any object thrown out from a running car moves backward from the car because the car is moving forward and hence with the frame of reference of a person sitting in a car, he will see that the object is moving backward.

Frequently Asked Questions

What is the relative speed of a bicyclist moving with a speed of 4m/s and a car at a speed of 75km/h moving away from each other?

Given: Speed of car V₁=75km/h= 20.83m/s

Speed of man V₂=4m/s

Hence, the relative speed of two diverging objects is

V=V₁-V₂

V=20.83+4=24.83 m/s

The relative speed between the two is 24.83 m/s.

What is the relative velocity of a kayak riding at a speed of 10 m/s against the river current of the speed of 8m/s?

The motion that is repeated frequently at an equal interval of time is called repetitive motion.

A single activity may be involving motions that reiterate every interval of time. Let us discuss some of the repetitive motion examples here in this topic as listed below:-

• Cycling
• Typing
• Walking
• Push-ups
• Paddling a boat
• Rubbing hands
• Heartbeats

Cycling

To keep the cycle in the momentum you need to continuously paddle the cycle.

The paddling of the cycle demands the repetitive motion of your legs. You continuously move your legs in a cyclic pattern, and the cycle moves forward in a linear motion.

Typing

While typing on a keyboard, your fingers constantly hit the keys on the keyboard. This motion occurs repetitively and hence is an example of repetitive motion.

You use the muscular force from the tip of your fingers and the joints of your hand while typing.

Walking

To walk a certain distance you put one leg forward and apply pressure on the ground from the other leg to push the body forward. The motion keeps on reiterating while walking. Also, you move your hand back and forth to balance the body while walking. This is also a repetitive motion by your hands.

Push-ups

A person doing push up will balance himself on two palms and toes and bring his body towards the ground and again push up his body and repeat this pattern several times.

Hence person follows repetitive motion while doing push-ups.

Paddling a Boat

In a paddleboat, you need to continuously paddle the boat to keep it in motion. Your legs move in a rhythm to paddle the boat and push the flow of water.

Rubbing Hands

Rubbing the hands together is a kind of repetitive motion.

You rub your hand moving back and forth constantly. Rubbing the hands generates heat warming your hand due to frictional energy.

Heartbeats

If you listen carefully to your heartbeat, the beats are in a rhythm appearing at a fixed interval of time. The heart pumps the blood continuously and hence is also a repetitive motion.

Chewing the Food

While chewing you repeatedly bites the food mixing saliva in the food particle to degrade it into smaller particles so that the food can be easily digested.

Hammering

You continuously hammer on the nail to fix it on the wall. The hand frequently moves back and forth to apply the force on the nail to push it into the wall.

Drawing Water from Well

To draw the water from the well using a pulley, you will pull the rope by your hand frequently toward yourself to draw the vessel full of water from the well. This is a repetitive motion.

The Collision between Air Molecules

The molecules in the air collide with each other frequently. The air molecules are separated from one another at a greater distance and hence are able to move freely around. Since the molecules are suspended in the air they collide with each other repeatedly.

Blinking Eyes

The blinking of eyes is a continuous motion of pupils and occurs at every interval of time. This helps in cleaning the eyes and prevents harmful contamination too.

Pendulum

The pendulum oscillates in a simple harmonic motion. The oscillation of a pendulum depends upon the mass of the bob, the length of the wire, and the angle of oscillation of a pendulum.

Upon giving an oscillation to the pendulum, it will keep on oscillating till it comes to a rest position as the energy is nullified. The oscillation of a pendulum is a repetitive motion too.

Swing

On giving a jerk to a swing, it will keep on oscillating. The energy of a swing decreases with every oscillation because the energy given to the swing is utilized to do the work to complete one oscillation every time.

Hand Fan

The hand fan is moves in a reciprocating manner to generate the waves of wind.

The wind force depends upon the speed of the hand motion that allows the repetitive motion of the hand fan in a semi arc curvature.

Clock

The second hand of the clock covers 6 degrees every second, the minute hand will cover 0.1 degrees per second and the hour hand travels 0.5 degrees per minute. Each hand repeatedly moves in a clockwise direction to cover a specific distance in a given interval of time.

Needle in a Sewing Machine

If you carefully observe the needle of the sewing machine, you will notice that the needle constantly moves up and down pinning the thread through the fabric.

Metronome

A metronome is a device used by the musician to listen to the beat and to keep the music in rhythm.

By adjusting the sliding weight to the tempo scale the periodic oscillation of the pendulum is maintained.

Opening and Closing Drawers

Opening and closing the drawers is also the repetitive motion we come across. The drawer can be opened by sliding the drawer out or by opening the lid of the case, anyways it is a one-way process and hence it occurs frequently.

Sawing

Sawing is a process to cut the wood into two pieces using a saw.

To penetrate the thin saw through the wood, the woodcutter continuously moves the saw back and forward to apply the friction and the pressure to run it through the wood and cut it into two.

Strumming Guitar

While playing the guitar you continuously strum the strings on the guitar using your right hand. This is a repetitive motion of plucking the string on every beat. The left hand is used to hold the note and chord on the fretboard.

Crushing the Nut in Mortar

To crush the nuts into fine particles, you repeatedly hit the pestle in the mortar. The repetitive motion of your hand is observed moving up and down to apply the pressure on the nuts in the mortar.

Frequently Asked Questions

Is the ocean waves near the shoreline an example of repetitive motion?

The ocean waves move in a transverse motion as well as in a longitudinal wave pattern.

The ocean waves hit the shoreline and go back into the sea. This process repeats at every interval of time and is a cause of erosion near the shore.

Is a ceiling fan an example of repetitive motion?

The ceiling fan rotates at a fixed axis and hence its motion is described as a rotational motion.

The rotations of the fan occur at a constant rate at the fixed voltage flowing through it and in a repetitive fashion hence its motion is repetitive motion too.

The first law of motion states that the objects tend to be in a state of motion or be in rest unless some external force is incident on the object.

The object cannot move or stop on its own. The force plays a major role in either displacing the object or bringing it to the rest. Let us discuss some of the first law of motion examples listed here below:-

Ping-pong Ball

The ping-pong ball conserves the momentum and the energy and hence it keeps on bouncing until it is made to stop. The sum of the kinetic energy and the potential energy of the ball remains the same on every bounce.

Newton’s Cradle

Newton’s cradle is designed with the bobs such that the momentum and the energy of all the bobs are conserved.

The bobs attached at both ends remain in motion at every interval of time and rest all the bobs in the middle are in a stationary position.

Brakes Applied to the Car

The car will stop accelerating immediately after applying the brakes. The car accelerates depending on the rotational speed of the gears. The engine of a car supplies the energy to the battery on the combustion of fuel.

Pulling or Pushing the Object

Upon applying pull or push force on the object, the object will displace from its initial position to the distance where it is pulled or pushed. The force required to move the object from its place depends upon the mass and configuration of the object.

Shopping Trolley

The shopping trolley in a mall is moved forward by applying the force and stops as we stop applying the force on it.

This follows the first law of motion too. The trolley has a wheel underneath. The circular curvature of the wheels makes it possible to sway the heavy load from the trolley.

Slider

A body sliding from the inclined slider will come to a rest when the force is exerted on it from the opposite direction. This force is exerted on a body as soon as the body touches the ground at the end of the slider and the body comes to a rest.

Raindrops

The raindrops will come to rest on meeting the ground and their kinetic energy is lost.

The raindrops approach from the cloud towards the ground due to the gravitational force of attraction of the Earth felt on the raindrops. The potential energy of the raindrop is converted into kinetic energy while making its journey toward the ground. On the force incident on the raindrop, it will come to a rest.

Ball

A ball accelerating will come to rest on applying the force over it. A stationary ball will be set into motion as the force is applied to the ball. To displace the ball from its place or to make it stationary at a place a force is required in both cases.

Bouncing Ball

The ball bounces back due to the force imposed on the surface of the ball by the ground. As the ball bounces on the ground the potential energy of the ball is converted into kinetic energy and it is bounced back into the air. This continues till the ball possesses potential energy.

Force Applied on Object Sliding Down

If the object is sliding down from a hill, its speed will keep on increasing if the shape of the object is round or cylindrical. To stop the object from sliding down a force has to be applied in a direction opposite to its motion.

Paddling for Cycling

To keep the bicycle moving you need to continuously apply the paddles.

If you stop paddling the bicycle will lose momentum and you will fall down. The cycle can be easily brought to a state of rest by applying a brake.

Striker on Carom Man

When you hit a striker towards the target carom man, the striker comes to a rest after hitting the carom man if the force exerted on the striker is sufficient. Upon hitting the carom man, the momentum of the striker is carried forward to the carom man and it moves from its place due to the exerted force from the striker.

Skiing

The skiing blade moves smoothly on the frictionless ice until the force is exerted by the stick in the skier’s hand on the ground. The sticks are used to guide the path and the direction and to slow down the speed as the speed of the skier increases if encountered a slope in between the path.

Swing

A swing will not oscillate until you give an initial push.

On applying push force you convert the potential energy of the body into kinetic energy and hence it starts oscillating.

Kicking a Football

A football will be in its state of rest until the player kicks the ball from its place. On kicking the ball you are actually supplying the kinetic energy to the ball to accelerate in a projectile motion.

Fan

A fan will be in a stationary position until you give an electrical power supply to set it into rotational motion. A fan rotates on a single axis of rotation. A capacitor of a fan stores a charge along with it, and hence it moves initially at a slow speed.

Hula Hoop

The hula hoop is a round circular hoop that you put around your body and give it a torque to rotate. If you stop it will lose its angular motion and it will fall down.

The angular speed of the hoop depends upon the number of torques given to the hoop in a given time interval.

Spinning Top

The precession of the spinning top is based on the angle between the azimuthal and spinning axis of the top and the torque given to the body for spinning. As the angle between the two increases, the center of gravity of the top points more and more away from its symmetric axis, and the momentum becomes zero.

Accident

When the two moving vehicles collide with each other or if the vehicle hits another heavy object the speed of the object becomes zero and the moving vehicles come to a rest. The force incident on the object is responsible to bring the fast moving vehicle to a stationary position.

Windmill

A windmill converts wind energy into electrical energy. The propellers of the windmill are stationary until the waves of wind hit the propellers and start rotating. These rotations are escalated by the use of shaft and motor.

Dart

A dart is accelerated towards the dartboard and comes to rest upon hitting on the surface of the board.

The dart has a pin at its end which pokes in the board. The depth at which the pin pokes in the board depends on the force and kinetic energy given to the dart throwing towards the target.

Pendulum

The Pendulum is at its resting position until it is perturbed by applying a force or giving it momentum. The oscillation of the pendulum comes to a rest decreasing its angle of oscillations gradually.

Stopping in Between a Walk

A person walking on a road suddenly stops in between is also an example of first law motion. A person applies a muscular force to bring his body to a rest position.

Apple kept on the Table

An apple kept on a table will be in its state of rest until some external force is applied to the apple to displace it from its position of rest.

The amount of force required to move the object also depends upon the shape and size of the object. For a rounded structure, less force is required compared to the same weighted object.

Skater Hitting on a Wall

The unprofessional skater, if hits on the wall by mistake, he will fall and come to a rest. A skater in a kinetic motion upon hitting on the wall will exert equal and opposite force on his body. On application of the force from the opposite direction, his body will come to a rest. If the impact of the force is more then he will obviously fall down.

Water Contaminated

The flowing water is moving with great mechanical energy. The flow of water will come to rest on meeting the volume of the water contaminated. As the volume of the water increases, the hydrostatic force between the molecules of water increases.

Hot Air Balloon

The hot air balloon moves in a direction of the flow of wind along with the air force. It continues to move with a wind flow.

If the direction of the wind changes it resists the motion of the balloon.

Dry Leave on a Node of a Tree

A dry leave is attached to the node of the tree and is at a stationary point. If the air resistance force is imposed on the node of the leaf then it will detach from the node and fall down.

Kayak on Stationary Water

Kayak will not move forward in stationary water if you stop rowing. The water has to push backing to move the kayak ahead along with your body.

Shoes on Rack

The shoes will remain stationary on the rack until the position of the shoes is changed.

Frequently Asked Questions

Why object remains stationary?

The stationary object follows Newton’s First law.

It will remain stationary until some force is exerted on its body. The force is an external source for the energy conversion of a body.

Why do some objects come to rest after moving a certain distance without applying force?

Some object travels a longer distance while some cover the shortest distance and come to a rest.

The objects are undergoing the forces that resist their motion depending upon the mass and shape of the objects. These forces are frictional force and air resistance.

The term ‘multiple-motion’ implies two or more motions at a time of an object.

Any object possessing more than one motion while performing a single task is said to have multiple motions. Here is a list of multiple motion examples that we are going to discuss in this topic:-

Spinning Top

The motion of the spinning top is a rotatory motion and at the same time, it moves in a parabolic curvilinear motion.

The angle between the axis of rotation and the azimuthal axis keeps on increasing during its precession and the point of the center of gravity of the spinning top directs outward from the line of symmetry. The precession of the top is faster before the top touches the ground decreasing its spin angular velocity.

Hitting the Marble

Marble is a small circular shape metallic or a glass ball. On hitting the marble, it will accelerate in a rotational motion moving in a straight path in a rectilinear motion. A round object when displaced from its place will rotate at the same time covering the path in a straight line.

Dancing

A dancer moves his hand and legs while dancing, performing different steps and motions hence it is a simple example of a multiple motion. A dancer uses muscular force and the potential energy driven from the stored chemical potential energy to utilize during the performance.

Riding a Bicycle

The bicycle can move in a rectilinear motion, circular motion, and curvilinear motion with the support of the two rotating tires in a circular motion.

To ride a bicycle, the muscular force is required to paddle the cycle to push the cycle ahead keeping the momentum and giving velocity to the bicycle to move.

Walking in a Moving Train

If you are walking in a moving train, your speed is in reference to the speed of the train and your direction of walking. Here we can have multiple motions.

Driving a Car

A car in motion is moving in its path at the same time there is a circular and rotational motion of the tires of the car. If the car is moving on a circular track then the motions in a picture is the circular motion and the rotational motion. If the car is in a straight path, then the motion of the car is a rectilinear motion, and the rotational motion of the tires.

Roller Coaster

Roller coasters have different path trajectories. We can have rectilinear motion, circular motion, curvilinear motion, etc.

The energy keeps on varying from kinetic to potential and potential to kinetic energy frequently during the flight on the coaster.

Bowling Ball

Upon throwing the bowling ball, the ball will spin towards the target in a spinning and rotational motion hitting the target and moving in a rectilinear motion. The momentum of the bowling ball depends upon the mass. The greater the mass of the ball, the more it will gain momentum based on the force applied while throwing the ball towards the target.

Horse Riding

Horse ridding is based on the third law of motion and the rectilinear motion of the riding horse.

The person sitting on the back of the horse exerts pressure on the back of the horse equal to the force felt in contrary from the horse. The person’s body accelerates up and down at the same time moving along with the riding horse.

Trolley

The trolley moves in a rectilinear motion but the wheels of the trolley moves in a centripetal as well as a rectilinear motion. The wheels of a trolley make it easy to carry a heavy load from one place to another.

Oceanic Waves

The oceanic waves are an example of longitudinal as well as transverse motion.

The molecules of the water on the surface oscillate up and down giving a wavy appearance. The oceanic waves hitting the shoreline come and return back to the ocean at every time interval.

Doing Exercise using a Gym Ball

Performing exercises with a gym ball involves multiple motions like the muscular movements of the body and the bouncing motion of the air-filled ball. There is an oscillatory motion due to the bouncing ball whereby acting the third law of motion on imposing the weight over it. At the same time, our body is performing various motions using the ball.

Skating

Skater has wheels below the shoes which rotate and push the body forward in a rectilinear motion.

If you increase the number of wheels beneath the shoes, then the rotational speed of the wheels will increase as the pressure of the body felt on each will be distributed among more wheels attached and the person will move forward with more speed.

Cricket Ball

A cricket ball on hitting moves in a projectile motion and rotational motion simultaneously. The ball spins continuously in the air with variation in the energy and the path of projection.

Fan

The fan rotates in a centripetal motion rotating at an axis fixed at one point contributing to the rotational motion.

If you hold a paper near the fan it will incline in a plane due to the force of a wind blowing in the upward and downward direction of the paper. The wind motion is in a rectilinear motion at some path.

Bouncing Ball and Moving Forward

A bouncing ball is in an oscillatory motion and in a transverse motion while it is moving forward. The ball bounces as some energy and its momentum are conserved. The potential energy acquired by the ball is converted back to the kinetic energy upon bouncing back on the ground and hence it rises up in the air again.

A Coin Tossed

A coin toss will rotate in an axis and move upward till its entire energy is converted into the potential energy and return down back following the same straight path. A coin is moving in rotational as well as rectilinear motion.

Billiard Ball

A billiard ball moves in a rotational motion as well as the rectilinear motion on the board upon hitting. Hence billiard ball is also an example of the multiple motions.

Drawing Water from the Well

While drawing water from a well using a pulley there is a continuous hand movement and the pulley moves in a centripetal motion.

The acceleration of the pulley depends upon the friction between the surface of the pulley and the rope based on the speed of hand motion.

Drilling

A drilling machine is used to make a hole in the objects. The drilling rod moves in a rotational motion while it moves within the object in a linear motion. It has a curve metallic work on the drill to remove the object particles from the hole formed on drilling through it.

The motion of the object in a curved path is called a curvilinear motion.

The velocity and energy of an object in a curvilinear motion are variable depending upon its path of projection. Let us discuss some of the curvilinear motion examples here below:-

Bicycle in a Curve Path

The bicyclist drives the cycle in a curve path by changing its direction of motion frequently, it follows the curve path and hence the motion of the bicycle is curvilinear motion. Any object moving in a curve path possesses curvilinear motion.

Waterfall from Cliff

The water falling from the cliff is in a curve arc.

The flowing water is in a mechanical motion. If the kinetic energy of the water is more, then it will travel a little further before making a fall. Hence, the waterfalls at a cliff show little curve falls.

Color Splash

The color mixed in water is filled in spray containers which on release move in a projectile path following a curvilinear motion. The distance at which the colored water will drop depends on the angle at which the water is sprayed.

Comet Approaching Solar Nebula

The comet approaching the Sun in the nebula follows the parabolic pattern.

It will approach the Sun by gradually increasing the speed, acquiring the potential energy from the radiations of the Sun that it receives, and then move away from the Sun gaining its own potential energy slowly moving away by increasing its speed following a curve path.

Boat Moving on Ocean Water

The boat moving on the ocean water on the oceanic waves will oscillate over the tides of water hence the motion of the boat is curvilinear motion. The boat moves on the surface of the water that follows the curve pattern and therefore the object traveling over the surface of ocean water is in a curvilinear motion.

Car Taking a Turn

A car taking a turn will follow a curve path. While taking a turn the centrifugal, as well as the centripetal force, is exerted on the car for that distance. The motion of the car on a curved path is a curvilinear motion.

Cricket Ball in the Air

The ball raised high in the air accelerates in a curve path. The kinetic energy of the ball is highest at the start and end of its journey in a curvilinear motion and the potential energy gained by the ball is the maximum at its greatest height from the ground.

Football Kicked from the Ground

The football on getting a kick will raise in the air following a curve path.

After bouncing on the ground some of its energy will reduce and the potential energy will again convert back into the kinetic energy and again it will rise in the air following the curvilinear motion. This will continue till the energy of the ball becomes nil.

Shot-Put

The shot put is the heavy metal ball used in sports activities. The person holds the ball across his neck and gives it an oscillation before making a throw in the air. The shot put travels in a curve path before making its fall.

Ocean Waves

The oceanic wave follows the curve path. This is due to the gravitation pull of the Moon exerted on the Earth. The tides appearing in the ocean are curved in shape. The molecules of the water oscillate in up and down motion frequently.

Boomerang

Boomerang is known for the curve path it follows and hence it returns back to the thrower on throwing it in the air.

The design of the boomerang is L in shape.

Javelin Throw

A javelin is a long rod with one end pointed. On releasing the javelin it moves in a curvilinear motion and the pointed end touches the ground marking the perpendicular distance that it covered.

Reptiles

The reptiles like snakes move in a curvilinear motion for locomotion. They will contract and relax the muscles that help to push their body forward forming a curvy motion.

Roller Coaster

You must have seen the roller coasters they are not designed for a straight-line path. They have curve paths,  circular paths, and zigzag motion to make your journey amazing experiencing variation in speed and heights.

While moving the coaster along the curve path, there is a variation in the kinetic energy and potential energy. Riding upward the speed decreases while accelerating down the speed of the coaster increases at a frequent rate.

Ball Bouncing and Moving Forward

The ball bouncing on the ground on making its throw in the air will move forward making a curve path. This is because of the conservation of energy by the ball in its flight which is why the ball bounces again and again till it loses its energy.

Catch the Ball

The children playing catch the ball throws the ball in a projectile motion that follows the curve path in a flight. The motion of the ball while playing passing the ball is a curvilinear motion.

Throwing Stone over the Mango

A stone is thrown towards the bunch of mangoes to pluck them from the tree and move in a curve path, hence following the curvilinear motion. The potential energy of the stone if it is the maximum will detach the mango from the tree upon hitting the target mango.

Basketball

A basketball thrown towards the basket will move in a curvilinear motion. The hoop is almost 10 ft above the ground.

Watering Garden using Pipe

If the pressure on the water in the watering pipe is more then it jumps to a far distance in a curve path. The water flowing from the pipe actually moves in a curvilinear motion. If the height of the water falling from the curve path is increased then some of the water molecules will jump up and travel short curve paths after bouncing on the ground.

Tea from Teapot

While filling the teacup with a tea from a teapot, the volume of the tea emerging out from the teapot will move in a curvilinear motion because of the shape and energy of the molecules of the tea in a pot.

Frequently Asked Questions

Does the velocity of the object in a curvilinear motion vary?

The energy of the object keeps on varying in the path of the object in a curvilinear motion.

The change in energy resembles the variation in the velocity of the object. The potential energy of the object is more at the crest of the curve and the velocity of the object is the minimum at this point.

Does the mass of the object affect the curvilinear motion?

The mass is a constant quantity and remains invariable.

The weight of the object may feel light or heavy depending upon the height at which the object is raised following the curvilinear motion in a vertical direction while the mass of the object remains unaffected.
