Kinetic Energy
... Note that the work in the work energy theorem (from yesterday’s class) is the work done on an object by a net force – it is the algebraic sum of work done by all forces. W = Ekf – Eki = ∆Ek *** So the change in kinetic energy is equal to the work done on or by an object*** ...

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.
