... Also, objects that aren’t moving or that are moving at a constant speed and in a straight line will keep doing what they’re doing unless an unbalanced force causes the motion to change. The baseball has low inertia (mass) and we can make it move with minimal force. It will just sit here unless an un ...

Why, then, do you have to keep pedaling your bicycle to maintain motion? • A space probe may be carried by a rocket into outer space. What keeps the probe going after the rocket no longer pushes it? • Y ...

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.
