Rotational Kinetic Energy

Kinetic energy of a rotating body.

Formula

KE=12Iω2KE = \frac{1}{2}I\omega^2

Variables

IMoment of inertia
\omegaAngular velocity

Example

Flywheels store this energy

Did You Know?

A rolling ball stores energy in both its motion and its spin, so it accelerates slower down a ramp than a sliding block.
