Question

Quizplus · Accepted Answer

Chemical rockets work based on Newton's third law of motion which states that "for every action there is an equal and opposite reaction". In a chemical rocket, the fuel and oxidizer are ignited to produce hot gases that are expelled out of the rocket nozzle at high speeds. This action generates an equal and opposite reaction, which propels the rocket forward.
