... A rocket can rise into the air because the gases it expels with a downward action force exert an equal but opposite reaction force on the rocket. As long as this upward force, called thrust, is greater than the downward pull of gravity, there is an unbalanced force in the upward direction that cause ...

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.
