Gravitational Potential Energy
... How much work does it take to lift an object? Well, work equals force times distance. The force you exert to lift something is equal to the object's weight, Fg=mg . Let's make up a new name for vertical distance--we'll call it height, with the symbol h. Then the work needed to lift something is W=mg ...

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.
