IMPACT is one way we see athletes express power.  It is when they have to make contact with another object. Impacting an opponent with high momentum is important in many parts of sports.

DRIVE relates to your ability to apply high levels of force during a rapid movement.

It is another measure of power that gives us insight into how hard you can deliver force into another person or object.

Drive is more about the total power you can develop while moving fast instead of relative to bodyweight. In physics terms its know as impulse or momentum.
