Question: State Law Of Conservation of Momentum."propellants are necessary for the working of rockets. " why?

Answer:

Law Of Conservation of momentum :-

It's also called 2nd law of motion.

Definition :

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as system's mass cannot change, so quantity cannot be added nor removed. Hence, the quantity of mass is conserved over time.

Propellants are necessary for the working of rockets because The thrust for the rocket continues as long as its engines are firing. Because propellant is burned up, the mass of the rocket changes during flight. Its mass is the sum of all its parts. Rocket parts includes engines, payload, control system, propellant tanks, and propellants. By far, the largest part of the rocket's mass is its propellants. But this mass constantly changes as the engines fire since the engines expell the used fuel in the exhaust plume.
