That's correct, einsteinian77. Since the rotational velocity v increases proportional with radius r (distance from center), you define the angular velocityOriginally posted by einsteinian77

Im guessing the velocity would be expressed in frequency somehow.

[nu] = v/r.

This is the same for all points. The unit is 1/s. You could also say it's radians per second, since by integrating you get the angle:

[alpha] = a/r

where a is the arc length, and [alpha] is measured in radians.
