Physics 30 – Mechanical Energy Unit REVIEW
... - A mass only has momentum if it is moving, and that momentum can be changed. - When a force acts on an object with momentum, it will change its momentum due to Newton’s first law. - The impulse is the measure of the force acting on the mass for a given time which causes the change in momentum. J ...

Circular Motion
... • Any object that revolves about a single axis undergoes circular motion. • The line about which the rotation occurs is called the axis of rotation. • In this case, it is a line perpendicular to the side of the Ferris wheel and passing through the wheel’s center. ...

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.
