What is acceleration?

AcademicPhysicsNCERTClass 9

The rate of the change of the velocity with respect to the time is known as the acceleration. 

If a body with initial velocity $u$ starts moving and its velocity becomes $v$ in time $t$ then 

Change in velocity $=v-u$

Acceleration $a=\frac{Change\ in\ velocity}{time}$

Or $a=\frac{v-u}{t}$

SI unit of acceleration is $m/s^2$.
