PeterDonis said:Ok, so from the standpoint of the center of mass inertial frame, you're transferring rotational kinetic energy to heat energy. Ok so far.
When you pay out a little bit of the cable and increase the separation of the masses, again from the standpoint of the center of mass inertial frame, does the angular velocity increase, decrease, or stay the same?
It goes down because L=I w, and L is fixed while I increases, so w decreases.
