6-2 Energy
... It is important to remember that gravitational potential energy relies only upon the vertical change in height, h, and not upon the path taken. In addition to gravitational potential energy, there are other forms of stored energy. For example, when a bow is pulled back and before it is released, th ...

... Example 9 The Moment of Inertia Depends on Where the Axis Is. Two particles each have mass and are fixed at the ends of a thin rigid rod. The length of the rod is L. Find the moment of inertia when this object rotates relative to an axis that is perpendicular to the rod at (a) one end and (b) the ce ...

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.
