UH Football Momentum

I went to the UH football game on Sat. when they played Idaho State. They killed Idaho really badly. Anyways, during the game I saw concepts that we have been learning in physics this chapter. In this picture, UH's offense is preparing for a snap against the defense of Idaho. When the offensive and defensive lines come crashing into each other this causes a sticky (also known as a inelastic) collision occurs. This means they stick together and their momentum is conserved. Also, right after the collision occurs, they have the same final velocity. When the lines do collide, each player has momentum, which is mass x velocity. So the player with the bigger mass and velocity will have the greater momentum. ( Thus most offensive and defensive lines are huge!) In the conservation of momentum, it states that when 2 things collide they transfer momentum so what one loses the other gains.
