Velocity is a measure of the rate of change of displacement. When an object moves from one position to another, it is said to be displaced. The value of displacement over time gives the velocity. Its direction is along the displacement. On the other hand, acceleration measures the rate of change in velocity. The object may change its speed or direction while keeping the speed constant. In both cases, it experiences acceleration. While acceleration refers to an increase in speed over time, its opposite, when the speed decreases with time, is called deceleration.
