Answer options
Correct answer and explanation
Correct answer: Linear momentum
Explanation: ā Correct Answer: D) Linear momentum š Explanation: Rocket propulsion works directly on the principle of the conservation of linear momentum, which heavily aligns with Newton's Third Law of Motion. As the rocket rapidly ejects hot exhaust gases downwards with high momentum, an equal and opposite upward momentum is imparted to the rocket. This powerful reactionary force propels the rocket forward into space.
