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.

The nozzle of a toy rocket is pointed down so that as fuel is ignited, the exhaust pushes down. Why is this necessary?

• The rocket is protected from the heat of the exhaust.

• Burned fuel can be collected on the ground.

• As fuel is combusted, the rocket pushes the gases backward and the gases push the rocket forward.

• This allows the rocket to be steered properly.
