So that would be the difference. The one absolute is force into the ground. When you look at top speed sprinting, you're going to push almost straight down into the ground. The higher the force into the ground in the shorter period of time, the faster you will run. From a vertical jump perspective, we need the same thing. I have to push harder into the ground so I can go in the opposite direction. The question is, is this a force per unit time, so the impulse, or is it the fact that you can't produce force into the ground? And so that's going to be the determining factor.
