Angular Momentum

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

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

Angular Momentum FORMULA

(Eq. 1)  \(\large{ L =  I  \omega }\)    

(Eq. 2)  \(\large{ L =  r  p }\)   

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:

\(\large{ p =  m v }\)
