Thee Physics of Thruss: Newton 's Third Law and d Rocket Dynamics

All thruss in space originates frem Newton 's third law of motion: for every action, there is an equal and opposite reaction. When a rocket engine expels mas - typically hot gas from pastionion or accessiates - at high velocity in one e direction; the spacecraft receives an equal push in thee opposite direction. This Relassip is quantified by thee rocket equation, which infiche change then velocity (1).
