How Can I Build a Rollercoaster?
... The first hill in a rollercoaster is always the biggest. Starting the rollercoaster on top of a high place allows the coaster to gain a lot of gravitational potential energy. That is, the amount of work an object will be able to do with the energy it gets from falling. Luckily, the coaster will be " ...

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.
