linear momentum is the answer

Answer 2

ANSWER:

The motion of a rocket is based on the principle of conservation of “Linear momentum”.

EXPLANATION:

Rockets are a fantastic illustration of Momentum Conservation which is Linear momentum. The exhaust gasses provide "momentum in one direction" so that the rocket itself has to obtain momentum in the other. The rocket fuel is continually burned instead of sending out.

The combustion of fuel produces gases at elevated temperature and pressure in a rocket. They flee through a nozzle with a big steady speed. The strong backward momentum of the gasses gives the rocket an equal forward momentum.
