Physics 50 Workshop
... The total energy at one instant in time = the total energy at any other instant in time. Usually these two times are final and initial, but the law applies to any two times. That might not look like an equation, so what you have to do is (1) identify all the different kinds of energy you might have: ...

... The two stars are in circular orbits, not about each other, but about the two-star system’s center of mass (denoted as O), which lies along the line connecting the centers of the two stars. The gravitational force between the stars provides the centripetal force necessary to keep their orbits circul ...

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.
