Kinetic energy in a spring arises from its movement. It depends on the spring''s mass and velocity. When compressed or stretched, a spring stores potential energy, which can be converted into kinetic energy when released. The spring constant, displacement, amplitude, period, and frequency influence both kinetic and potential energy.

Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy ; adding energy to the system correspondingly results in an …
