If the velocity of an object continues to increase, the rate of increase in velocity is called **acceleration**.

## Acceleration Formula

If the initial velocity of a moving object is u and after t Time later the final velocity of that object is v, then the acceleration of that object (f) = the final velocity of the object (v) - the initial velocity of the object (u) / the elapsed time (t).

I.e. acceleration of the object, f = (v-u) / t

## Dimensions of acceleration

The dimensions of acceleration are **M ^{0}LT^{-2}**.

## What is the unit of acceleration?

- Units of acceleration in C.G.S system is
**Centimeters/second**.^{2} - Units of acceleration in S.I (
**MKS**) system is**meters/second**.^{2} - Units of acceleration in FPS system is
**feet/second**.^{2}

## Quantity of acceleration

Acceleration is a vector Quantity.

## What is the difference between acceleration and velocity?

Velocity | Acceleration |
---|---|

Velocity is defined as the motion of an object in a specific direction. | Acceleration is defined as the change in velocity of an object over time. |

Displacement / time | Velocity / Time |

meters/second | meters/second^{2} . |
