(e) The computation of Wg does not use the new information (that U = 100 J at the ground), so we again obtain Wg = 167 J. (f) As a result of Eq. 8-1, we must again find U = –Wg = –167 J. ...

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.
