first law: an o-lineman standing on the line of scrimmage gets tackled to the ground second law: a wide receiver sprinting down the line to catch a hail mary pass third law: a d-lineman and o-lineman pushing each other back and forth (for o) to keep the d-lineman away from his quarterback
When the QB puts forward force on the ball and then lets go, the ball wants to keep moving forward. The more force he puts on the ball the more inertia it will have. And the more mass the football has the more force has to be put on it. :)
