Angular Momentum

angular momentumAngular momentum, abbreviated as L (also called rotational momentum or moment of momentum), is how much an object is rotating around a fixed point.

Angular Momentum FORMULA

\(\large{ L =  I \; \omega }\)    

\(\large{ L =  r \; p }\)   


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

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

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

\(\large{ p  }\) = linear momentum

\(\large{ I  }\) = moment of inertia

\(\large{ m  }\) = object mass

\(\large{ v  }\) = object velocity

Solve for:

\(\large{ p =  m \; v }\)
