Rotational Kinetic EnergyEdit

The rotational kinetic energy is defined as follows:

$ E_r = \frac {1}{2} I {\omega}^2 $

Alternate ways to write this are:

$ E_r = \frac {1}{2} \frac {L^2}{I} $

$ E_r = \frac {1}{2} L \omega $

Angular MomentumEdit

The angular momentum of an object is defined as follows:

$ L = I \omega $
