PS Energy and Work
... The amount of work necessary to elastically deform an object is equivalent to the energy stored in that object. There is an equivalent relationship between work done by a net force acting on an object and the energy of the object. Consider that energy associated with the work done by a net force doe ...

4.2 Fluid Friction Notes
... The fluid pressure in the wake is less than the fluid pressure in the flow. The lower pressure in the wake causes a force to act on the object (boat or car) in the opposite direction to its velocity. This pressure difference in a wake is called pressure drag. Frictional drag and pressure drag b ...

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.
