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.

As 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 flywheel will not work, then the main supply will fail, i.e. when there is no supply of energy or zero supply of energy.
