Answer 1

The "Why Does a Rocket Work?" section of "What Is a Rocket?" likely describes the forces that push a rocket forward. In particular, it would explain the principles of thrust and how rockets generate propulsion by expelling gas at high speed in the opposite direction, thereby following Newton's third law of motion: for every action, there is an equal and opposite reaction.
