Work & Energy
... If we add these two results together, we arrive at 0J of work done on the system by all the external forces acting on it. Alternatively, since the speed is constant, we know that there is no net force on the system. ...

... The natural tendency of any object is to resist changing state of motion. This is called inertia. For example, if an object is moving, it likes to keep on moving. If an object is stationary, it likes to remain stationary. It takes some measure of force to change this tendency. Are some objects capab ...

7-3 Moment of Inertia and Angular Momentum
... Newton’s first law says that inertia is the tendency of an object to stay at rest or remain in motion in a straight line with a constant speed unless acted upon by an unbalanced force. Similarly, an object that is rotating tends to continue spinning at a constant rate unless an unbalanced force acts ...

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.
