Physics 110 Homework Solutions Chapter 7
... (1) Force × distance is called work. Work, like force and impulse, produces a change in a quantity of motion of a body. In the case of work, the motion is describe by the kinetic energy. (2) In order for a force to do work on a body, the body must undergo a displacement that is, at least, partly in ...

... It means that the force exerted on the particle 2 by particle 1 is an attractive force, pulling #2 toward #1. Gravitational force is a field force: Forces act on object without a physical contact between the objects at all times, independent of medium between them. The gravitational force exerted by ...

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.
