# Rotational Kinetic Energy

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

### Rotational Kinetic Energy formula

$$\large{ KE_r = \frac {1}{2} I \omega^2 }$$

Where:

$$\large{ KE_r }$$ = rotational kinetic energy

$$\large{ \omega }$$  (Greek symbol omega) = angular velocity

$$\large{ I }$$ = moment of inertia
