What is angular momentum?
... is no net torque (the forces are internal)so L is a constant but the moment of inertia changes and since L = Iω as I decreases ω increases. So if I decreases by a factor of 2 then ω increases by a factor of 2. The kinetic energy is = Iω2 so if I decreases the kinetic energy increases by the amount o ...

... 9. Find the moment of inertia (I) of two 5 kg bowling balls joined by a 1-meter long rod of negligible mass when rotated about the center of the rod. Compare this to the moment of inertia of the object when rotated about one of the masses. (The moment of inertia of each ball will be considered as mr ...
