Accelerationis the measure of change in velocityof an object per unit time. Accelerationmay becaused either by change indirection of motion orchange spead or both
"Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing."
