## Angular Momentum

Angular momentum ( $$L$$ ) (also known as rotational momentum) is how much an object is rotating.

### Angular Momentum FORMULA

$$\large{ L = r p }$$

$$\large{ L = I \omega }$$

Where:

$$\large{ L }$$ = angular momentum (rotational momentum)

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

$$\large{ p }$$ = linear momentum vector

$$\large{ r }$$ = vector length, directed from the center of rotation to the momentum point

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