According to Newton's Third Law, if someone is riding a wakeboard and then jumps off, the wakeboard will travel in the opposite direction because...

• the mass of the wakeboard is the same as the person jumping off

• the pull of gravity on the person is sthe same as on the wakeboard

• the air resistance on the person is great and the friction on the wakeboard is small

• for the force that sent the person forward, there is an equal force pushing back on the wakeboard.
