Rocket engines can obtain momentum with fuel additives known as "oxidizers." These substances enhance the combustion of fuel, allowing for more efficient propulsion. Common oxidizers include liquid oxygen and ammonium perchlorate, which help to increase the energy output of the rocket engine.

How many rocket engines did the Saturn V have?
The Saturn V rocket had five rocket engines in its first stage, called the F-1 engines. These engines were responsible for providing the necessary thrust to lift the rocket off the ground and into space.
How does a rocket get off the ground?
A rocket gets off the ground through a process called ignition. Once the rocket's engines are ignited, they generate thrust, which propels the rocket upwards. The thrust created by the engines overcomes the force of gravity, allowing the rocket to lift off the ground and enter into space.
What is the bottom part of a rocket called?
The bottom part of a rocket is called the "rocket stage" or "first stage." This part contains the engines and fuel necessary for liftoff and initial ascent. After its fuel is expended, it typically separates from the rest of the rocket to reduce weight for the subsequent stages.
What is a rocket with 2 or more stages is called?
A rocket with 2 or more stages is called a multi-stage rocket. Each stage contains its own engines and fuel supply, and is jettisoned once its fuel is depleted to reduce the overall weight of the rocket. This allows for more efficient use of fuel and higher altitude and velocity capabilities.
What kind of force is it when rockets escape from gravity?
If the rocket has a certain speed, it will escape from gravity due to its own momentum. To speed the rocket up, currently chemical combustion is used. The burning gas goes out in one direction, thus pushing the rocket in the opposite direction.If the rocket has a certain speed, it will escape from gravity due to its own momentum.

What is the force that accelerates a rocket called?
The combustion of rocket fuel ejects a mass of material at high velocity. In accordance with Newton's third law, the momentum of the ejecta generates an equal and opposite reaction - which propels the rocket forward.
What is the name of the force that pushes a rocket upwards?
thrust

What is the force that is created by a rocket called?
The force created by a rocket is called thrust. Thrust is generated by the expulsion of gas at high speed from the rocket's engines, following Newton's third law of motion: for every action, there is an equal and opposite reaction. This thrust propels the rocket upward against the force of gravity.
As the rocket is moving through the Earths atmosphere another force acts against the thrust from the shuttles engines. What is this force called?
Reaction force that is equal and opposite to thrust force from the rocket's engine.
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
What is momentam?
The moment of linear momentum is called angular momentum. or The vector product of position vector and linear momentum is called angular momentum.

Which kind of rocket engines are used on the space shuttle and why?
Space Shuttle Main Engines (SSME) are Rocketdyne RS-24 liquid-fuel rocket engines powered by liquid hydrogen and liquid oxygen. The Solid Rocket Boosters used during ascent are solid fuel rockets manufactured by Thiokol Corporation fueled by a mixture of ammonium perchlorate oxidizer, aluminum, an iron oxide catalyst and polymers as a binding agent.
