... force of friction acts on the disk as it rolls downhill. For both objects the moment of inertia I remains unchanged (the objects don’t change shape) and the angular velocity vz increases, so Lz = Ivz increases. Conservation laws are great when they apply, but remember that they do not apply in all ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
