It's actually not angular acceleration, it's angular velocity.

Can't be dude. Re-read your basic mechanics. For *any* object to go in a
circle it's 'accelleration', otherwise there is no way to take into account
the change in vector of the velocity vector which is always chaning
(precessing in a circle). Last time I checked anytime a velocity vector
changed that was an accelleration (dv/dt).
