Question

rocket works on principle of conservation of what

Answer 1

What principle of conservationdoes rocket work on? Conservation of momentum — or Newton's third law of motion in disguise. If you accelerate a small amount of gas in one direction, it pushes back with an equal and opposite force, accelerating your much larger spaceship at a proportionately smaller rate.

Answer 2

Rockets work on the principle of conservation of momentum. The rockets gain momentum equal to the momentum of the gas expelled from the engine but in opposite direction they continue to expel gases after the rocket has begun moving and hence rockets continue to gain more and more momentum so instead of traveling at steady speed they get faster and faster as long as engines are operating. The acceleration of rocket is given as
