# Angular Momentum

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Angular momentum is how much an object is rotating.

## FORMULA

$$L = r p$$

$$L = I v_a$$

Where:

$$L$$ = angular momentum

$$r$$ = vector length, directed from the center of rotation to the momentum point

$$p$$ = linear momentum vector

$$I$$ = moment of inertia

$$v_a$$ = angular velocity
