Quizplus · Accepted Answer

The force that accelerates a rocket in outer space is exerted by the exhaust gases expelled from the rocket's engines, also known as thrust. The thrust propels the rocket in the opposite direction to that of the exhaust gases leaving the rocket, in accordance with the third law of motion (action and reaction). The rocket's nose cone and wings play a role in aerodynamics but do not generate the force that accelerates the rocket in outer space where there is no atmosphere.
