What do you mean by effective jet velocity of a rocket?
How momentum cause rocket propulsion and how rocket accelerates in space vacuum?
If we start from newtons third law, we can get the idea of action and reaction is equal and opposite It is its' fuel ejection that enables the rocket to fly forward. P=MV But here mass is decreasing due to the consumption of fuel thus, we are now flying at P= (M-m)V WHERE M grater than (M-m) hence the rocket clearly is moving at a constantly decreasing mass with constant velocity. therefore it clearly accelerates as time goes.

How is it possible for a rocket to propel itself through space?
This is possible via the conservation of momentum. A rocket ejects matter from its back and this matter carries momentum. To conserve momentum the rocket must gain an equal amount of momentum in the opposite direction. Since momentum is related to velocity this causes the rocket to move. This is basically an application of Newton's third law. You might have been confused with the situation in air. For example an airplane moves through air by pushing air past it (using its propeller). This accelerates the air, and thus increases its momentum. The airplane must therefore gain momentum in the opposite direction, and accelerates itself as well. The only difference between the airplane and the rocket is that the rocket carries the stuff it accelerates (and ejects) while the airplane can use the air that is already present all around it. Note that while this is the basic explanation, the situation with the rocket is made somewhat more complicated by the fact that as the rocket loses fuel it also loses momentum because momentum is velocity times mass and the lost fuel lowers the mass of the rocket. You might want to look up Tsiolkovsky's rocket equation if you want more information.

Why rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket accelerates in an opposite direction?

Stages of a rocket going into space?
The stages of a rocket going into space: The first stage of a rocket is used to acquire the acceleration of a rocket. When the fuel of the first stage is exhausted ,it detaches from the rockets and drops off. The velocity at this stage becomes the initial velocity of the second stage .Now the second stage is ignited ,the rocket gains acceleration and it's velocity foes on increasing . The removal of the surplus mass contained in the first stage helps in attaining the higher velocity .When the fuel of the second stage is exhausted ,it too detached from the rocket .Finally at the third stage , the rocket starts off with the required velocity.
How does a rocket stay in orbit or continue into outer space?
The gravitational pull of Earth is the main factor that a rocket must overcome. A rocket must reach a certain velocity or speed and direction to orbit or escape the Earth. For a rocket to orbit the Earth, it must have enough thrust to reach orbital velocity. Orbital velocity is the speed and direction a rocket must travel in order to orbit a planet or a moon. The lowest possible speed a rocket my go and still orbit the Earth is about 8km/sec. If the rocket goes any slower, it will fall back to Earth.For a rocket to travel beyond Earth orbit, the rocket must achieve escape velocity. Escape velocity is the speed and direction a rocket must travel to completely break away from a planet's gravitational pull. The speed a rocket must reach to escape the Earthis about 11km/sec.

What makes a rocket move forward in Roblox?
The way rockets work is by modifying the velocity and body-gyro of the rocket brick. In simplified terms, after thee rocket is "created" the script detects and saves the direction the rocket is pointing.The script uses the body gyro to lock the rocket brick in the said direction and suspend the rocket in the air; then it modifies the velocity to propel the rocket forward.
