Chapter 6 Newton`s Laws with Friction, and Circular Motion
... We should note here, that these laws of friction are empirical laws, and are not exactly like the other laws of physics. For example, with Newton’s second law, when we apply an unbalanced external force on a body of mass m, that body is accelerated by an amount given by a = F/m, and is always accele ...

Static Friction

There is a limit to the magnitude of static friction, so eventually you may be able to apply a force larger than th ...

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.
