What is angular momentum?
... The dominant physical law is conservation of angular momentum. There 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 ...
