Newton's third law is the foundation of rocket propulsion. According to this law, for every action, there is an equal and opposite reaction. In the case of a rocket, burning fuel inside the rocket's engine produces a high-speed stream of gases as the action. As a result, the rocket experiences a reaction force in the opposite direction, propelling it forward. Newton's second law is also involved in determining the acceleration of the rocket based on the mass of the rocket and the force produced by the engine.
