ANGULAR MOMENTUM


So far we’ve developed rotational analogs for displacement, velocity, acceleration,
and force. We will finish by developing a rotational analog for linear momentum;
it’s called angular momentum.


Consider a small point mass m at distance r from the axis of rotation, moving with
velocity v and acted upon by a tangential force F.
