How do flywheels store energy?
The physics of flywheels. Things moving in a straight line have momentum (a kind of "power" of motion) and kinetic energy (energy of motion) because they have mass (how much "stuff" they contain) and velocity (how fast they''re going). In the same way, rotating objects have kinetic energy because they have what''s called a moment of …
