Question

Rocket works on the principle of conservation of 1)Mass 2)Energy 3)Velocity 4)Momentum

Answer 1

1. Momentum:

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.

So for example, the 3,270 ton Saturn V was able to accelerate gently off the pad against the pull of gravity by hurling fifteen tons of propellant per second out its tailpipe at nearly ten times the speed of sound. But that meant the rocket got lighter by 15 tons per second, so that the same amount of thrust caused it to accelerate faster and faster.
