  • How to Calculate Power Based on Force and Speed

    In physics, you can calculate power based on force and speed. Because work equals force times distance, you can write the equation for power the following way, assuming that the force acts along the direction of travel: where s is the distance traveled. However, the object's speed, v, is just s divided by t, so the equation breaks down to.
