Acceleration is defined as the rate of change of velocity with respect to time.

## Acceleration

The rate of change of velocity with respect to time is known as acceleration. According to Newton’s second law, the ultimate consequence of all forces applied to a body is its acceleration. The frequency at which a body’s velocity changes is defined by acceleration, which is a vector quantity. Acceleration can be expressed by the formula

a = Change in velocity / Time taken

The S.I unit for acceleration is meter per second square or m/s2.
