In inertial energy storage systems, energy is stored in the rotating mass of a fly wheel. In ancient potteries, a kick at the lower wheel of the rotating table was the energy input to maintain rotation. The rotating mass stored the short energy input so that rotation could be maintained at a fairly constant rate.
