It's actualy not velocity, it's angular accelleration.

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).

No, it's actually not angular acceleration, it's angular velocity.

Constant rotation = constant angular velocity = zero angular acceleration.
The vector of angular velocity is parallel to the axis of rotation, and is
constant throughout the rotation.  There is linear acceleration as you
describe, but we're discussing angular.

Now, Einstein, enough pedantics - go build something.  ;)
