When explosion of gases creates pressure resulting in motion of a rocket, the force pushing the rocket is called what?

• Correct Answer: temperature
• friction
• stasis
• thrust

Explanation: For a long time, many people believed that a rocket wouldn’t work in space. There would be nothing for the rocket to push against. But they do work! Fuel is ignited in a chamber. The gases in the chamber explode. The explosion creates pressure that forces the gases out of one side of the rocket. The rocket moves in the opposite direction ( Figure below ). The force pushing the rocket is called thrust .
