... can see how quickly an object gains speed as it falls. It travels at about 10 m/s after one second, 20 m/s after two seconds, 30 m/s after three. This translates to speeds of about 36, 72 and 108 km/h after just three seconds. Objects won’t really fall quite this fast for the same reason that a feat ...

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.
