Force and Motion
... 8. Two objects in motion have different masses. How does the difference in mass affect the forces needed to make the objects achieve the same rate of change of velocity? a. The object that has less mass will require more force to achieve the same rate of change. b. Force does not affect the rate of ...

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.
