Acceleration is known as rate of change of velocity, (change in velocity in given interval of time)for example when a body is free fall under gravity then the body increase its velocity of 9.8 m/s in every 1 sec until it reaches to the ground. Then its change in velocity in given time is acceleration, it's acceleration is 9.8m/s2
