## velocityA vector quantity specifying both the speed and direction of movement of an object in a given frame of reference. The magnitude of velocity is the scalar quantity speed ( S), related to distance (s) and time (t)
by the equation S = s/t; similarly velocity (v)
is related to distance and time by v = ds/dt.
Angular or rotational velocity is given by ω = dθ/dt.
