... Consider an isolated system with two particles that do not have any external forces exerting on it. What is the impact of Newton’s 3rd Law? If particle#1 exerts force on particle #2, there must be another force that the particle #2 exerts on #1 as the reaction force. Both the forces are internal for ...

Rotational Inertia and Angular Momentum
... Because the direction of something rotating is hard to determine, physicists say that the direction of angular momentum is in the plane of the rotation. If this wheel was rotating, we would say its angular momentum is pointed in this direction. So it would want to stay rotating in that 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.
