Review C: Work and Kinetic Energy
... Two critical points emerge. The first is that only change in energy has meaning. The initial or final energy is actually a meaningless concept. What we need to count is the change of energy and so we search for physical laws that determine how each form of energy changes. The second point is that we ...

... There are two types of an equilibrium state when sum of all forces on a body equals zero. One is static when two bodies are at rest with respect to each other. While in Muftk’s industrial application we achieve this condition that both bodies gain rotation in equilibrium. Both bodies e.g. wheels cen ...

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.
