Rotational Kinetic Energy

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Rotational kinetic energy, abbreviated as \(KE_r\), is the energy an object has because it is rotating and does not matter if its moving from one place to another.

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
