In physics, speed is defined as the rate of increase (or decrease) of distance travelled, with time. Linear velocity is the rate of increase (or decrease) of distance traversed by a body in a particular direction. Speed is defined with the omission of reference to direction. Thus, velocity is a vector quantity and speed is a scalar one.
