Newtons Third Law

Q. How does a rocket move?
A. A rocket move by a gas that turns into heat, which causes the rocket to push up into the air.
Q. What is Newtons Third Law?
For every action, there is an equal and opposite reaction.  Imagine a person standing on a skateboard. Imagine that person throwing a bowling ball. The ball will go forward. The person on the skateboard will move, too. The person will move backward. Because the person is heavier, the bowling ball will move farther.
