How momentum cause rocket propulsion and how rocket accelerates in space vacuum?
TariqJamal
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.

light in a vacuum
When fire needs oxygen to burn then how the fire in the rocket burns in space?
Fire does indeed need oxygen to burn in the presence of atmospheric air on Earth. However, the fire in a rocket burning in space is different from the typical combustion that occurs on Earth. The flames we see when something burns on Earth are the result of combustion involving oxygen from the surrounding air. In space, there is no atmospheric air, and therefore no free oxygen available for combustion. So, if you were to light a match or a candle in the vacuum of space, it wouldn't produce a flame as we know it on Earth. However, rockets are equipped with their own oxidizers, which are substances that provide the necessary oxygen to support combustion. The most common rocket fuel used is a combination of liquid or solid fuel and an oxidizer, such as liquid oxygen (LOX), liquid hydrogen, or solid propellants. In the case of liquid oxygen, it is stored onboard the rocket in a separate tank from the fuel. When the rocket engines are ignited, the fuel and oxidizer are mixed and ignited together in a controlled manner. This chemical reaction releases a large amount of energy, creating hot gases that are expelled through the rocket's nozzles at high speeds, providing the necessary thrust for the rocket to move forward. Since rockets carry their own oxidizers and don't rely on atmospheric oxygen, they can operate in the vacuum of space, where there is no air or atmosphere. This allows them to travel beyond Earth's atmosphere and into space.
What are the gases contained in a vacuum?
Theoreticaly there are no gasses in a total vacuum
What is a volume empty of free molecules?
a vacuum

If it is a perfect vacuum, any amount of it will have zero pressure.If it is a perfect vacuum, any amount of it will have zero pressure.If it is a perfect vacuum, any amount of it will have zero pressure.If it is a perfect vacuum, any amount of it will have zero pressure.
Does the vacuum have an acceleration and momentum?
no just acceleration
Does the velocity of an object increase when its falling freely in a vacuum?
It accelerates at a higher rate
When a spaceship accelerates in the vacuum of space what does it push against?
The spaceship pushes against the hot gases that are exiting out the rocket engine. This is similar to how you are pushing against the brick that you throw while you are standing on a skateboard. You go the opposite direction of the brick.
What is a space ship?
A spaceship is any vehicle that can leave the planet and travel in the vacuum of outer space. This can be as simple as a rocket or as complex as an intergalactic ship capable of running on antimatter. Modern spaceships are rocket-powered, but science is working on different types of fuel and propulsion, so you may see different sorts of spaceships in the near future.

Why do feather and rock hit the ground at the same time in vacuum?
Basically, gravity accelerates both at the same rate.
How does a rocket change its speed in space with no air?
Some people (who have not studied physics) believe that rockets work because the rocket exhaust pushes against the air, and therefore in the vacuum of space where there is no air, rockets won't work - but that is not the case. Rocket exhaust doesn't need to have air to push against. The expanding gases in the rocket's exhaust nozzle push against the rocket. The gas has its own mass and its own inertia, and the change in momentum of the exhaust gas causes an opposite change in momentum of the rocket. This can be difficult to grasp because we think of gas as being virtually weightless, but a large rocket can emit literally tons of exhaust. The fact that it is in the form of a gas doesn't change the result; mass is mass, whether solid, liquid, or gas.This is WRONG, rocket DOES work in space.From NASA"A rocket is a type of engine that pushes itself forward or upward by producing thrust. Unlike a jet engine, which draws in outside air, a rocket engine uses only the substances carried within it. As a result, a rocket can operate in outer space, where there is almost no air."How it accelerate"Rocket engines generate thrust by putting a gas under pressure. The pressure forces the gas out the end of the rocket. The gas escaping the rocket is called exhaust. As it escapes, the exhaust produces thrust according to the laws of motion developed by the English scientist Isaac Newton. Newton's third law of motion states that for every action, there is an equal and opposite reaction. Thus, as the rocket pushes the exhaust backward, the exhaust pushes the rocket forward.The amount of thrust produced by a rocket depends on the momentum of the exhaust -- that is, its total amount of motion. The exhaust's momentum equals its mass (amount of matter) multiplied by the speed at which it exits the rocket. The more momentum the exhaust has, the more thrust the rocket produces. Engineers can therefore increase a rocket's thrust by increasing the mass of exhaust it produces. Alternately, they can increase the thrust by increasing the speed at which the exhaust leaves the rocket."http://www.nasa.gov/worldbook/index.html

Can you please direct me to were I can get a vacuum diagram for a 1996 Seville
In Robert Goddard's time what did people mistakenly believe was necessary for a rocket to work?
They believed that a rocket needed air to push against. Robert Goddard tested a rocket in a vacuum and proved them wrong.
