... In the SI system (metres, kilograms, seconds) the unit of speed is the metre per second. This is not the only unit that can be used. Some alternative, equally correct units are mile per hour, kilometre per hour, centimetre per minute, etc. All of these have one thing in common: each is a unit of len ...

... passed through 360°, or 2π radians. Then the sine function resumes its previous path. Thus, when ωt = 2π, the time interval t is equal to the period T, or T = 2π/ω seconds. Since f is the reciprocal of T, f = ω/2π cycles per second. For reciprocating machinery the frequency is often expressed as cyc ...

Newton’s first law: A body at rest remains at rest, and a body in motion remains in motion at the same velocity in a straight path when the net force acting on it is zero. Therefore, a body tends to preserve its state ...

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.
