Acceleration:

Acceleration is defined as the rate of change of velocity of a body.

Acceleration= $\frac{Change \: in \; Velocity}{Time \; Taken}$

Acceleration= $\frac{Final Velocity \: - \; Initial Velocity}{Time \: Taken}$

             a= $\frac{Vf \: - \: Vi }{T}$

Unit of acceleration:

          SI unit of acceleration is metre per second squared (ms^-2)

USEFUL INFORMATION

Acceleration of a moving object is in the direction of the velocity of its velocity is increasing. Acceleration of the object is opposite to the direction of velocity if its velocity is decreasing.
