In simpler terms:

* Figure out how much the velocity changes: This means subtracting the initial velocity from the final velocity.

* Divide that change in velocity by the time it took: This gives you the rate at which the velocity changed, which is the acceleration.

For example, if a car speeds up from 0 to 60 miles per hour in 5 seconds, its acceleration would be:

* Change in velocity: 60 mph - 0 mph = 60 mph

* Time: 5 seconds

* Acceleration: 60 mph / 5 seconds = 12 mph/second
