Question 17

If you jump off of a diving board, are you exerting force on the board or is it exerting force on you?
Actually, as you stand on the end of the board or as you push off from its end, you are pushing on the board and it is pushing back on you. The forces you exert on one another are exactly equal in amount but opposite in direction. That observation is called Newton's third law of motion and is the real meaning behind the phrase "for every action there is a reaction."
