This video teaches how to calculate the acceleration of a car. The information for this calculation is for a car that accelerates by 12 meters per second in a time of 3 seconds. So to calculate acceleration use the following formula: acceleration equals change of speed divided by time. So, using the information provided for this calculation, acceleration equals 12 meters per second divided by a time of 3 seconds. So this gives an acceleration of 4 meters per second squared.
