Gravity: the Laws of Motions
... Mass and Weight • Mass is a measure of how much material is in an object. • Weight is the force exterted by gravity on a massive body (body with mass), e.g. placed on the surface of Earth • Weight is a measure of the gravitational force exerted on that material. • Thus, mass is constant for an obje ...

PowerPoint Lesson
... A force is something that is capable of changing an object’s state of motion, that is, changing its velocity. Any particular force may not actually change an object’s state of motion, as there may be other forces that prevent it from doing so. However, if the net force—the vector sum of all forces a ...

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.
