Acceleration is defined as the rate of change of velocity with respect to time. It is a vector quantity, meaning it has both magnitude and direction.
Acceleration (a) = Change in velocity (Δv) / Change in time (Δt)
The fundamental quantities involved in acceleration are:
- Length (L) for velocity, which is measured in meters per second (m/s)
- Time (T) for time, which is measured in seconds (s)
Therefore, the unit of acceleration is meters per second squared (m/s^2).
For example, if an object's velocity changes from 10 m/s to 20 m/s in 5 seconds, the acceleration can be calculated as follows:
Acceleration = (20 m/s - 10 m/s) / 5 s
Acceleration = 10 m/s / 5 s
Acceleration = 2 m/s^2
So, the acceleration of the object is 2 m/s^2.

Acceleration
Acceleration is a vector quantity that describes the rate of change of velocity of an object. It is measured in meters per second squared (m/s²).
Acceleration can be calculated using the following formula:
```
a = (v - u) / t
```
where:
- `a` is acceleration
- `v` is final velocity
- `u` is initial velocity
- `t` is time
Example:
A car accelerates from rest to a speed of 20 m/s in 5 seconds. What is the acceleration of the car?
```
a = (v - u) / t
a = (20 m/s - 0 m/s) / 5 s
a = 4 m/s²
```
Therefore, the acceleration of the car is 4 m/s².
