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 ```
