Motion under gravity - The Open University
... resistance is negligible. In fact, air resistance is negligible for many practical purposes, so our calculations here won't be too unrealistic. If an object falls a certain distance, work will be done on it by the gravitational force that is acting on it. This work will cause the kinetic energy of t ...

... As was pointed out earlier, the last term on the right hand side of equation (8.30) is responsible for the Coriolis effect. This effect is the source for some well-known motions of the air masses. To see how this happens, let’s consider the xyz coordinate system to be located at some latitude ! wher ...

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.
