Question

Which of Newton's 3 Laws explains a rocket lifting off? *

Law of inertia
Law of Acceleration
Law of Action-Reaction

Answer 1

Newton's Third Law states that "every action has an equal and opposite reaction". In a rocket, burning fuel creates a push on the front of the rocket pushing it forward. This creates an equal and opposite push on the exhaust gas backwards.

Answer 2

Newton's Third Law of Motion

Step-by-step explanation:

A rocket expels hot gases at a very high pressure very quickly, and these gases have lots of energy, and according to Newton's third law, every action has an equal and opposite reaction. So, expel lots of gas at a high rate, and the energy of the gases being pushed out propels the rocket upward. Hope that helps!
