Speed – definition, formula, Examples | Instantaneous speed | Average speed | velocity

Speed definition – Speed is defined as the rate at which a particle covers a distance along a given path. It is given by the ratio of distance travelled to the time taken. Speed formula – Distance travelled (s)/Time (t) Note Since distance travelled is a scalar, the speed of a particle is also a scalar. The unit of speed is cm s^-1 in C.G.S. system and m s^-1 in M.KS. or S.I. system. …
