... The best system is usually diKerent from the one that would be chosen for a work-energy approach. The reason for this difference lies mainly in the way in which force transfers work and impulse. A force can only do work by moving, but it can 'do impulse' all the time. Therefore, when the system is s ...

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.
