In skateboarding, when you kick off a curb to get yourself moving so you can start your rad routine, what law of physics are you demonstrating?

Newton's Third Law of Motion states that "for every action there is an equal and opposite reaction." When you push off with your foot to get your board moving, you're sending the same amount of energy into the curb from your leg muscles.
