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 formulas

\(\large{ L =  I \; \omega }\)   
\(\large{ L =  r \; p }\)  

Where:

\(\large{ L  }\) = 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:

\(\large{ p =  m \; v }\)
