Rotational kinetic energy
... Objective: The kinetic energy of a rotating disk and falling mass are found; the change in their kinetic energy is compared with the change in potential energy of the falling mass. The conservation of energy principle, states that these changes are equal in magnitude and opposite in sign. This exper ...

... takes a large force to change their motion. Once they are moving, it takes a large force to stop them. • On your way to school, a bug flies into your windshield. Since the bug is so small, it has very little inertia and exerts a very small force on your car (so small that you don’t even feel it). ...

Is it possible to do work on an object that remains at rest?
... So in the first case, we have: 1/2 m (302 - 02) = 1/2 m (900) In the second case, we have: 1/2 m (602 - 302) = 1/2 m (2700) Thus, the bigger energy change occurs in the second case. ...

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.
