A flywheel used in machines serves as a reservoir, which stores energy during the period when the supply of energy is more than the requirement and releases it during the period when the requirement of energy is more than the supply.
The force impulse is given by the change in momentum, i.e., ΔP = F.Δt. where P is momentum and t is time.
In the same way, the power impulse is given by the change or fluctuation in energy, i.e., ΔE = P.Δt. where P is power and t is time.
Thus, smooth out power impulses mean the smoothness in the fluctuation of energy, which is the work of a flywheel.
Note: A flywheel stores energy when the supply of energy is less than the required, but the flywheel will not work, then the main supply will fail, i.e., when there is no supply of energy or zero supply of energy.

The function of a flywheel is to smooth out power impulses.
A flywheel is a rotating mechanical device that stores rotational energy. It consists of a heavy wheel or disk that is mounted on an axle and is used to reduce fluctuations in rotational speed. The primary function of a flywheel is to smooth out power impulses in machines and systems.
Why power impulses need to be smoothed out?
In many machines and systems, power is not generated or used at a constant rate. Instead, there are often fluctuations in the power supply or demand. These fluctuations can cause variations in the rotational speed of the machine, leading to inefficiencies and potential damage to the system.
The role of a flywheel in smoothing out power impulses:
1. Inertia: The flywheel's large mass provides inertia, which helps to maintain a more constant rotational speed. When the power supply or demand fluctuates, the flywheel's inertia resists these changes, minimizing the impact on the system.
2. Energy storage: The flywheel stores excess energy during periods of high power supply or demand and releases it during periods of low supply or demand. This helps to balance out the power fluctuations and maintain a more consistent output.
3. Energy transfer: The flywheel acts as a buffer between the power source and the load. It absorbs energy from the source during high-power periods and transfers it to the load during low-power periods. This transfer of energy helps to smooth out the power impulses and ensure a more stable operation.
4. Damping vibrations: In addition to smoothing out power impulses, a flywheel also helps to dampen vibrations in the system. The rotation of the flywheel absorbs and dissipates vibrations, reducing noise and improving overall system performance.
Applications of flywheels:
Flywheels are commonly used in various machines and systems where power fluctuations occur, such as:
- Automobile engines: The flywheel helps to smooth out the power impulses generated by the engine's pistons, ensuring a more consistent rotation and minimizing engine vibrations.
- Power generation systems: Flywheels are used in some renewable energy systems, such as wind turbines, to store excess power during high wind speeds and release it during low wind speeds, ensuring a more constant output.
- Industrial machinery: Flywheels are often used in heavy machinery, such as presses and stamping machines, to maintain a consistent rotational speed and minimize impact forces.
In conclusion, the primary function of a flywheel is to smooth out power impulses in machines and systems by providing inertia, storing and transferring energy, and damping vibrations.
