As a rocket travels upwards the engine thrust remains constant but the mass of the rocket decreases Why?
The primary answer is that a rocket under constant acceleration is using up fuel, so it's mass decreases as the fuel is spent.
What fuel is in a model rocket engine?
Solid fuel
What is crygenic engine?
A liquid-fuel rocket or a liquid rocket is a rocket with an engine that uses propellants in liquid form.
What is the fuel in a rocket engine?
keroscene
Why don't the rockets on a spaceship melt the metal?
Some, or all of the fuel circulates through a cooling jacket around the rocket engine before it is burnt and this cools the rocket's engines. But there might be more to it than that.
Where does a solid fuel rocket store it's fuel?
in the engine
Why do engineers need to keep the mass of a spacecraft as low as possible?
The heavier it is the stronger the engine has to be. And the stronger the engine the more fuel will it burn. And the more fuel it burns the more fuel has to be carried in the rocket. And the more fuel the rocket has to lift the stronger the engine has to be.

What is a rocket igniter?
A device that ignites the fuel & oxidizer mixture in the rocket engine when a "burn" is to begin.it lights the rocket.
A rocket uses an engine that creates thrust through the combustion of a liquid fuel and an oxidizer. What kind of rocket is this?
Chemical rocket
A rocket uses an engine that creates thrust throughout the combustion of a liquid fuel and an oxidizer what kind of rocket is this?
Chemical rocket
How rocket engines work?
A rocket engine is a reaction engine as the fuel is burnt the thrust created pushes the rocket forward. Newton's 1st law in action; for every reaction there is a equal and opposite reaction.
