a = (v_f - v_i) / t

where:

* a is acceleration

* v_f is final velocity

* v_i is initial velocity

* t is time

Explanation:

* Acceleration is the rate of change of velocity over time.

* The difference between the final velocity and the initial velocity gives us the change in velocity.

* Dividing this change in velocity by the time it took to occur gives us 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:

* This formula only applies to motion in a straight line (linear motion).

* If the acceleration is constant, then this formula can be used to calculate the acceleration over any time interval.

* If the acceleration is not constant, then this formula can only be used to calculate the average acceleration over the given time interval.
