The '''conservation of angular momentum''' holds that the angular momentum just prior to a collision is the same as the angular momentum just after a collision.

== Example ==

Imagine a rod of length l and mass M suspensed from one end vertically, and that a mass having velocity v and mass m collides with the other end and sticks to it. The maximum angle of displacement of the rod from the vertical axis can be calculated using the '''conservation of angular momentum''':

:<math>\mathbf{L_i}=\mathbf{L_f}</math>

:<math>\mathbf{m}\times{v}\times\{l}= \mathbf{I}\times{\omega}</math>
