a = (v - u) / t

Where:

* a is acceleration

* v is final velocity

* u is initial velocity

* t is time taken

Explanation:

Acceleration is the rate of change of velocity over time. It tells you how quickly an object's velocity is increasing or decreasing.

* (v - u) represents the change in velocity.

* t represents the time it takes for that change in velocity to occur.

Therefore, dividing the change in velocity by the time taken gives you the acceleration.

Units:

* Acceleration is typically measured in meters per second squared (m/s²).

* Velocity is measured in meters per second (m/s).

* Time is measured in seconds (s).

Note:

* If the acceleration is positive, it means the object is speeding up.

* If the acceleration is negative, it means the object is slowing down (also known as deceleration).
