The kinetic energy set the object into motion; the sound is created on collision of the two or more inelastic objects.
We will discuss some of the example of kinetic to sound energy with detailed facts listed here below:-
Tuning Fork
The tuning forks were used to tune the musical instruments. On hammering the fork on the rubber, the vibrations are set up in the fork that is transmitted through the air molecules and the sound is generated.

Drumming
The motion of the drum stick is the kinetic energy that is converted to sound energy upon hitting the drum. The vibrations are carried by the air molecules in the surround and hence the drum can be heard for a range of distance.
The propellers of the fan at a speed set the surrounding air into kinetic motion. These air molecules exert a frictional force on the surfaces of the propellers which is converted to sound and heat energy. At high speed, this frictional force is more and hence the sound heard is also more.
Helicopter
You must be familiar with the rotor blades sound coming from the helicopters. This sound is also created because of the airflow at different pressure.
As the blades start rotating, the high pressure region is generated below the rotors and low pressure above it which result in the lift of the helicopter. Because of the pressure difference and the friction of air, the sound is generated.
Gushing wind
You must have heard the whispering sound when the velocity of the wind is high. This whispering sound is generated as the air passes through small openings or bounces on the body.
The waves over the sea pass the shoreline and go back to the sea. You can hear the ocean roars, this is due to the waves from the ocean.
Leaves
As the air blown towards the trees, the leaves, and tender part of the plant set into motion. The sound is generated as the leaves swirl along with the air.
It is a nice seashell you may find near the Southern Oceans. It has a cavity in the middle and a vacant space.
Due to the swirling body, the air passing through the cipre produces a marvelous sound as if the water is flowing inside the cipre.
Flowing Water
The flowing water bodies accompany the kinetic energy with it, which produces sound energy and we can hear the flow of water. The same is not true for the pond or swimming pool water.
As the current passes through a coil and the magnetic field is produced that consequences in the repulsion and attraction of the magnet and hence produce an audio effect.
Mosquito Wings
That irritating buzzing sound from the mosquitoes is due to the vibrations produced by their wings. The frequency of the sound is in the range of 300-400 Hz. This vibrational kinetic energy is converted into sound energy.
Vehicles
You must have noticed the sound of the vehicles while passing by on the road. This is due to the frictional force adverse on the tires and road and the air resistance. This kinetic energy results in sound energy.
To play each note or chord on the guitar, we have to keep our fingers in motion. The movement of fingers per beat is associated with the kinetic energy of your finger.
As you run your fingers on the keyboard, the kinetic energy of the fingers is turned into the sound energy as the sound is generated as you press the keys over the keyboard.
Due to the friction, the sound is produced. Also, the body undergoes air resistance force as you push your body forward through the air.
Turbines
Turbines are used to derive the energy from the wind, water and steams using a generator. The kinetic energy of the turbines as it starts rotating gives out sound energy due to the frictional force and the pressure difference region that is created due to the rotational motion.
Roller Coasters
The unpleasant sound from the roller coasters is due to the dental metal that is mechanized below the roller that assures the safety of the riders which produces a frictional force too.
The sound is created due to the vibrational energy set into the particles.
The back and forth movement of the molecules present in the air transverse these vibrations producing sound and a sound wave to travel through the medium.
How sound is different from noise?
The sound wave is the vibrations that travel through the medium and reaches the listener’s ear.
This sound wave travels forming the region of compression and rarefaction. If two or more sound waves intersect together, then the noise it produces.

Identifying the Variables in the Pulley System
Before we delve into the calculations, it’s essential to identify the variables involved in a pulley system. These variables include the mass of the objects connected to the pulley, the acceleration due to gravity, and the coefficient of friction, if applicable. By understanding these variables, we can proceed with the necessary calculations.
Applying the Force Formula for Pulley
To calculate the tension force in a pulley system, we can use the concept of Newton’s second law of motion. According to this law, the net force acting on an object is equal to the mass of the object multiplied by its acceleration. In the case of a pulley system, the tension force in the rope connected to the pulley generates acceleration in the objects it supports.
Steps to Calculate Tension Force
To calculate the tension force in a pulley system, follow these steps:
Identify the objects connected to the pulley and the system’s configuration. Determine the masses of these objects and any relevant coefficients of friction.
Draw a free-body diagram for each object, considering the forces acting on them. These forces include the weight of the objects (mg), any frictional force (if present), and the tension force in the rope.
Apply Newton’s second law of motion to each object. Write down the equations based on the forces acting on them.
If the pulley system involves multiple objects connected to the same rope, ensure that the tension force in the rope is the same for all objects.
Solve the equations simultaneously to find the tension force in the pulley system.
Worked-Out Examples on Finding Tension Force in a Pulley System
Let’s explore some worked-out examples to solidify our understanding of how to find the tension force in a pulley system.
Example 1: Simple Pulley System
Consider a simple pulley system where two masses, m1 and m2, are connected by a rope passing over a pulley. If m1 = 5 kg and m2 = 3 kg, and the system is frictionless, we can calculate the tension force.
The free-body diagram for m1 includes the weight force (m1 * g) and the tension force (T).
The free-body diagram for m2 includes the weight force (m2 * g) and the tension force (T).
Applying Newton’s second law of motion to both objects gives us two equations:
m1 * g – T = m1 * a
T – m2 * g = m2 * a
Since the tension force (T) is the same for both objects, we can combine the equations and solve for T.
Example 2: Complex Pulley System with Different Masses
Imagine a more complex pulley system with three masses, m1, m2, and m3, connected in a series by ropes passing over pulleys. If m1 = 10 kg, m2 = 5 kg, and m3 = 8 kg, we can find the tension force in such a system.
The free-body diagram for m1 includes the weight force (m1 * g) and the tension force (T1).
The free-body diagram for m2 includes the weight force (m2 * g) and the tension forces (T1 and T2).
The free-body diagram for m3 includes the weight force (m3 * g) and the tension force (T2).
Applying Newton’s second law of motion to all three objects gives us three equations.
By combining the equations and solving for T1 and T2, we can find the tension forces in the system.
Example 3: Pulley System with Friction
Now, let’s consider a pulley system with friction. Suppose two masses, m1 = 6 kg and m2 = 4 kg, are connected by a rope over a pulley with a frictional force acting on it. To find the tension force in this system, we need to account for the frictional force.
The free-body diagram for m1 includes the weight force (m1 * g), the tension force (T), and the frictional force (Ff).
The free-body diagram for m2 includes the weight force (m2 * g) and the tension force (T).
Applying Newton’s second law of motion to both objects gives us two equations.
Since the tension force (T) is the same for both objects, we can combine the equations and solve for T, considering the frictional force.

Motors are devices that convert electrical energy into mechanical energy, typically through the interaction of magnetic fields. However, by reversing this process, we can harness the mechanical energy produced by a motor to generate light.
To achieve this, we can connect a small generator to the motor. As the motor spins, it generates mechanical energy, which is then converted into electrical energy by the generator. This electrical energy can then be used to power a light bulb, illuminating our surroundings.
This process demonstrates the conversion of mechanical energy to light energy through the intermediary of electrical energy. It showcases the interconnectedness of different forms of energy and how they can be transformed to serve various purposes.

Therefore, the light bulb emits 18,000 joules of radiant energy during the 5-minute period.
Calculating Radiant Energy for Heat
Calculating radiant energy for heat follows a similar principle. The formula for calculating radiant energy for heat is:

The Stefan-Boltzmann constant is a fundamental constant in physics, denoted by σ (sigma), with a value of approximately 5.67 × 10^-8 W/(m^2·K^4). The surface area refers to the area over which the heat is radiated, and the temperature difference is the difference between the initial and final temperatures. Let’s look at an example to understand this calculation better.
Example:
Suppose we have a metal plate with a surface area of 2 square meters (m^2). The plate is initially at a temperature of 100 degrees Celsius and is allowed to cool down to a final temperature of 50 degrees Celsius over a period of 10 minutes (600 seconds). To calculate the radiant energy emitted by the metal plate, we can use the formula mentioned earlier:
Radiant Energy = Stefan-Boltzmann Constant × Surface Area × Temperature Difference^4 × Time
Radiant Energy = 5.67 × 10^-8 W/(m^2·K^4) × 2 m^2 × (100 – 50)^4 × 600 s
Radiant Energy = 2.56 × 10^6 J
Therefore, the metal plate emits 2.56 × 10^6 joules of radiant energy during the 10-minute period.

Food supplies a lot of chemical energy that is stored in our body in the form of potential energy which is then converted into mechanical energy when we are doing some activities like walking, running, jumping, pulling, pushing, etc.
Clocks
The clocks have a battery. The chemical energy derived from the batteries is supplied to a motor that runs thus converting chemical to electric energy first and then this motor runs the gears on the clock mechanism that causes the hands of the clock to move by converting electrical energy in the form of mechanical energy.
Gunpowder is used to supply the mechanical energy to the bullet on firing. The chemical energy of the gunpowder is turned into heat energy and then to the mechanical energy to the bullet.
Firecrackers
The firecrackers come with the highly reactive chemical powder that upon ignite makes a blast heat the system.
The ejection of the missiles or the containers causing the explosions in the upward direction is because the heat released gives out the mechanical energy to the missiles.
Rockets
A lot of energy is required to lift the rocket into space making an upwards thrust.
This energy is supplied to the rocket by the chemical injected into its body. The fuel is ignited to produce a high amount of heat energy enough for it to take its flight vertically with very high speed.
The energy released from the chemical can be directly used to do mechanical work or it may convert into some other form of energy which is then used to derive the mechanical energy.
