Question

What is the working principle of rocket ?

Answer 1

Newton's third law of motion: For every action there is an equal and opposite reaction. <br /> As a reaction to the fast ejection of exhaust fluids through the nozzle, an upward thrust is created. Thus thrust helps the rocket to propel upward.<br /> Once propelled, it maintains its motion according to the law of conservation of momentum- the initial momentum= final momentum.
