### 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.

### 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.
