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 M0LT-2.
What is the unit of acceleration?
- Units of acceleration in C.G.S system is Centimeters/second2 .
- Units of acceleration in S.I (MKS) system is meters/second2 .
- Units of acceleration in FPS system is feet/second2 .
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/second2 . |
