How do flywheels store energy?

Just as the kinetic energy of an object moving in a straight line is given by this equation: E = ½mv 2 (where m is mass and v is velocity), so the equivalent, kinetic energy of a spinning object is given by this one: E = ½Iω 2 (where I is the moment of inertia and ω is the angular velocity).

4.1: Energy and Metabolism

Even a slow-moving wrecking ball can do a great deal of damage to other objects. Energy associated with objects in motion is called kinetic energy (Figure (PageIndex{4})).

Definition and Classification of Energy Storage Systems

KESS (Kinetic Energy Storage Systems)

Kinetic Energy Storage Systems (KESS) are based on an electrical machine joined to a Flywheel.
