Explain how a rocket is kept in motion.
Fuel is burst in a combustion chamber and exhaust gases are expelled at high velocity. This causes a large backward momentum. From the principle of conservation of linear momentum, an equal forward momentum is gained by the rocket.
Due to continuous combustion of the fuel, there is a large change in forward momentum which lead to the thrust, hence maintaining the motion of the rocket.
