17 Examples Of Sliding Friction


The sliding friction examples, which are commonly observed all around us as sliding friction occurs in objects of all sizes, are listed below:

Pushing an Object across the Surface

When we push the stationary object across the surface of another object, we applied force to it. The applied force displaced an object from a stationary position, and then an object gradually starts to pick up a speed.
However, if you noticed, even after pushing an object, its motion is still opposed by specific resistance? This resistance is called the sliding friction, produced between the surfaces of two objects; it acts opposite to the sliding motion.

Any Types of Motion when Objects are in Contact

Sliding friction is the reaction force to the applied force, caused when the surfaces of two objects are in contact.
Newton’s laws of motion explain the motion of an object in sliding friction as,

  • An object is accelerated to move with sliding motion when the applied force is greater than sliding friction.
  • An object is slow down when the applied force is lower than that of sliding friction.
  • An object moves with constant velocity when the applied force is equal to that of sliding friction.

Vehicle Braking Mechanism

The braking mechanism is the most advanced sliding friction example, which prevents us from major vehicles accidents.
When you want to stop the running vehicle while driving, its brake generates sliding friction inside its wheel, which slows down the running wheels. Because of the sliding friction, the vehicle’s tires still push against the road’s surface, but in slower motion than the sliding motion.

Sliding of an Object in an Inclined Plane

Inclined plane, one of the simple machines, illustrates the concept of sliding friction better.

The use of an inclined plane makes any work easier by reducing the force required for lifting the heavy object and saving mechanical energy. But sliding friction on an inclined plane allows an object to slide from the height safely or without causing any damage.

Rubbing both Hands Together

When we rubbed our both hands together, especially during winter, it produces heat due to sliding friction between surfaces of both hands.
Similarly, if any two objects are rubbed together, the amount of heat generate depends on the materials of both surfaces.

Lighting a Matchstick

Lighting a matchstick is an extraordinary sliding example found in our home. It is inspired from one of the ancient examples of sliding friction. The stone age man had generated the fire for the first time when he slides two stones together like we create the fire by sliding the matchstick on the rough surface of the box.

Opening a Window

We applied our muscular force to open the window, which shows its sliding motion. But the rails on which window slides offer sliding friction in the opposite direction between the surfaces of the window and rails. The sliding friction restricts the sliding motion of the window to prevent it from damage.

Cleaning the Surface

While cleaning dirt on the surface of any furniture or floor, we slide a cloth on it. When the cloth surface slides on the floor or furniture surface, it causes sliding friction as both objects are in physical contact.

Pushing the Bottle across the Table

When we have to pass the bottle or any utensil to another person while having dinner, we push it across the dining table.
The force applies to the bottle after we pushing it, causes the bottle to slide across the table. In reaction, the contact of surfaces between bottle and table generates sliding friction that opposes the unnecessary sliding motion of the bottle.

Pulling Vegetable Drawer of the Fridge

Pulling vegetable drawer is one of the common sliding examples we found at our home. When we apply muscular force on the drawer by pulling it towards us, its lower surface slides on the fridge’s surface. In reaction, the contact between surfaces of drawer and fridge causes sliding friction towards the fridge that prevents it from displacing directly from the fridge.

Sliding Friction Examples in Daily Life

The sliding friction examples in daily life include various activities we do every day that unknowingly create sliding friction. Such sliding friction examples in daily life are listed below:

Walking

Walking is one of the most common sliding friction examples that we create every day. How? Let’s see
When we start to walk, we actually push the ground by applying a muscular force. In reaction to the applied muscular force, the contact between our foot and ground created sliding friction – allowing us to move forward without sliding on the ground.

Swiping on Mobile Devices

Due to the constant demand of technology, every person using a mobile device creates sliding friction without even realizing it.
To perform a particular task on a smartphone mobile, we need to slide our finger on its screen, also called swapping. The sliding activity generates sliding friction between the surfaces of our finger and mobile screen, preventing any damage to the screen.

Erasing using a piece of Rubber

The example of erasing using rubber is similar like we rubbed both hands to generate heat.
To erase any writing mistakes on the paper, we apply the muscular force on the rubber by holding and then sliding it several times on the paper. The sliding activity generates the sliding friction between surfaces of rubber and paper, which erases the writing mistakes due to molecular interactions between surfaces.

Children sliding on the Playground Slides

The playground slides having less sliding friction on their surfaces than inclined plane slides. That’s why the playground slides are only used for entertainment purposes.
When the children slide from the height on the playground slides, the less sliding friction between surfaces of children’s bodies and playground slides prevents them from directly falling into the ground and gives them thrilling experiences.

Drifting the Car

Drifting of a car means essentially making a turn at too higher a speed.
While drifting the car, sliding friction between the surface of the tires and the road’s surface binds the car to the road by gripping the car’s front tires first and then back tires, which prevent it from skidding along the straight road.

Solving a Rubik’s Cube

A Rubik’s cube is a 3-D combination Puzzle game that shows us sliding friction in daily life. To solve the puzzle, we apply a muscular force to the puzzle by sliding multiple cubes. This sliding activity creates the sliding friction in the opposite direction between both surfaces of cubes, allowing us to slides it safely.

Coins sliding in the Carrom Board

The carrom is Indian origin game that is played indoors on the tabletop.
To earn the points in carrom, we have to place the coins into the holes at the corners of carrom by hitting it with the striker. When we hit the coin, we apply a muscular force on it, which makes the coin slides towards the direction of the force applied. The sliding activity of the coin creates sliding friction between surfaces of the coin and carrom that prevent it from sliding towards the hole. Therefore, the boric powder is spread throughout the caroom surface before starting the game to reduce the sliding friction.

Long Jump Athlete slide across the Sandpit

One of the unpopular sliding friction examples is when the long jump athlete slides across the sandpit. The athlete accelerated themselves by running before jumping, and after completing the jump, they required specific force to stop their motion. Therefore, when the contact between the athlete body and the surface of the sandpit occurs, it creates sliding friction between them, which prevent them from sliding too far.

What Causes Sliding Friction?

Sliding friction is caused by the following factors of the objects, which can be summed up into coefficient of sliding friction and normal force acting on a sliding object: 

Factors affecting Sliding Friction
What causes Sliding Friction?

Smoothness or Roughness of the Surface

Due to the roughness of the surface, any object can easily slide over on it. But the sliding friction is mainly caused due to irregularities between the surface of the objects. Thus, the more roughness the surface has, the greater the sliding friction between the surface and an object. The roughness of the surface can be estimated from the coefficient of sliding friction.

Adhesiveness of Surface

Adhesiveness is the essence of sliding friction. When the surface of two objects is in contact offers surface adhesion to each other, it contributes to increasing the sliding friction between them. The amount of sliding friction generation depends on how adhesive the surfaces of the object are.

Surface Deformation

Due to deformation like wrinkles or cracks on a solid surface, it caused more sliding friction than air or water.

Amount of Pressure by Forces on either Object

When two objects slide on each other, the normal force acts on either object that applies the pressure on its sliding surfaces. This amount of pressure by normal force increases the interaction between the surfaces, resulting in more sliding friction.

Weights of the Objects

Since the normal force acting on an object is proportional to its weight, the sliding friction due to normal force is also indirectly proportional to the object’s weight.

Relative Speed between Objects when they make Contact

When two objects make contact and start slides or rubbed on each other, their relative speeds increase with the temperature. The increase in speeds exceeding a safely specified value of speed increases the sliding friction between objects.

Other Factors

Factors like its chemical bond or electromagnetic attraction and repulsion also play a significant role in creating sliding friction in specific conditions.


FREQUENTLY ASKED QUESTIONS (FAQs)

How is Sliding Friction used in Everyday Life?

Ans: Sliding friction opposes the sliding motion between two objects, which is helpful to us to do some activities safely in our everyday life as follows:

  • In playground slide, it stops the kid from falling immediately
  • In a water slide, it enables the thrill while sliding without any danger.
  • It avoids skidding of vehicles
  • Using brake, it used to stop the vehicles

What is the Relationship between Sliding Friction and Speed?

Ans: The coefficient of sliding friction of an object increases with its speeds when that object having elastically soft materials slides on other smooth surfaces.

Therefore, the frictional force of sliding friction is directly proportional to the velocity.

Is Ironing Sliding Friction?

Ans: The ironing of any cloth is done with a sliding motion, and it involves sliding friction between cloths and hot metal of iron. 

Therefore, ironing is one of the sliding friction examples.

Why Rolling Friction is less than Sliding Friction?

Ans: The rolling friction between the object and surface is less compared to their sliding fiction.

The frictional force between surfaces depends on its point of contact. The rolling object makes less contact with the surface than the sliding object, which results in less rolling friction than sliding friction.
