Rotating Stool
If the masses are pulled in, the moment of inertia is considerably decreased.
Conservation of angular momentum
dictates that the angular velocity must increase.
The
moment of inertia
is large with the masses held out. For a given
angular momentum
, the
angular velocity
is relatively low.
