... - Values of s and k depend on nature of surface. - s and k don’t depend on the area of contact. - s and k don’t depend on speed. - s, max is usually a bit larger than k. - Range from about 0.003 (k for synovial joints in humans) to 1 (s for rubber on concrete). See table 5.2 in book. ...

Chapter 4 Oscillatory Motion
... It should be noted that ω (and hence T and f) does not depend on the amplitude A of the motion of the mass. In reality, of course if the motion of the mass is too large then then spring will not obey Hooke’s Law so well, but as long as the oscillations are “small” the period is the same for all ampl ...

How do forces act on objects? • An object will not start moving unless a push or pull acts on it. • Objects in motion will continue to move unless a push or pull changes that motion. • Newton’s first law is also called the law of inertia. • Inertia is the tendency of all objects to resist any change ...

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.
