### Explanation

Like velocity, acceleration is a vector quantity and has both magnitude and direction. The velocity of an object is the speed of an object moving in a definite direction. Acceleration is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.

Acceleration = Change in Velocity/ Time taken

SI unit: ms2

Following is the table of acceleration vs velocity:
