**Difference between Velocity and Acceleration**

Velocity is the rate of displacement of an object. Acceleration is the rate of change of velocity of an object. This is the main difference. Other differences are:

**Velocity **

- The rate of change of position in a definite direction is called velocity and is denoted by v
^{→}. - If the time interval approaches zero, the rate of change of displacement with time is called velocity
- In S.I. and M.K.S. system unit of velocity is metre/sec (ms
^{-1}) - Dimension of velocity = [LT
^{-1}] - If force is not applied on a moving body, it travels at uniform velocity along a straight line.

**Acceleration**

- The rate of increase of velocity is called acceleration and is demoted by a
^{→}. - If the time interval approaches zero, the rate of change of velocity with time is called acceleration.
- In S.I. and M.K.S. system unit of acceleration is metre/sec
^{2}= (ms^{-2}). - Dimension of acceleration = (LT
^{-2}). - If force does not act on a moving body, it will have no acceleration.
