Velocity is the displacement made per unit of time.

If direction or speed of the object change it causes change in velocity.

Acceleration is the term used for measuring the change of velocity. Acceleration is the change of velocity per unit of time.

Acceleration can be described as changes in speed, changes in direction, or changes in both. Acceleration is a vector.
