... If Fext = 0 for this system then W = 0, but we know that DK is not zero as the ball falls.. So where is the energy coming from to increase its kinetic energy? We associate what is called a Potential Energy Ug with the configuration of the earth particle system, the change of which is the negative of ...

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.
