Skiing and External Forces
... Note that the steeper the slope the larger G1 will become, therefore the skier will accelerate more rapidly. As a ski is tipped up on edge it penetrates the snow and the snow presses back on the ski causing it to bend. The force from the snow pushing on the ski causes the skier to change direction. ...

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.
