unlike solid fuel, liquid fueled rockets are capable of being throttled, shut down, and restarted.

Where do some rockets get their oxygen from?
Liquid fueled rockets get it from liquid oxygen, and solid fueled rockets get it from and oxidized metal.
Does rockets use fossil fuels?
Yes, they use fossil fuels and they use liquid hydrogen and liquid oxygen.
Which fuel is used in rockets?
There are two three types of fuel used in rockets 1) Solid fuel - an aluminum powder used for an initial boost into space. 2) Liquid fuel - usually super-cold liquid hydrogen and oxygen is used is the Space Shuttle's main engines during launch. 3) Hypergolic fuel - Monomethylhydrazine and Nitrogen Tetroxide does not need a source of ignition. It is mainly used for maneuvering in space.
What is the fuel in rockets?
Liquid oxygen and liquid hydrogen are used as the propellant in the high efficiency main engines of the Space Shuttle. LOX/LH2 also powered the upper stages of the Saturn V and Saturn 1B rockets. Another cryogenic fuel with desirable properties for space propulsion systems is liquid methane.
What kinds of fuel do liquid fuel rockets use?
Liquid rockets can use a single liquid, two liquids or, rarely, three fuels (more correctly called propellants). The most common type uses two propellants, generally one liquid fuel and one oxidizer -- such as liquid hydrogen (fuel) and liquid oxygen (oxidizer).
Where do some rockets get their oxygen from?
Liquid fueled rockets get it from liquid oxygen, and solid fueled rockets get it from and oxidized metal.
Why is oxygen needed by rockets and how do they get it?
Oxygen is used in liquid-fueled rocket motors as a combustion product, usually in conjunction with liquid hydrogen as well. In space, Oxygen is extremely thin at extreme altitudes, and it only occurs in space at the molecular level. It isn't enough to sustain the combustion of a liquid-fueled rocket motor once it enters the upper atmosphere without being fed liquid oxygen.
How can you use oxygen in rockets?
Liquid oxygen and liquid hydrogen are used as rocket fuel, oxygen gas is used by the astronauts to breath.
Why do rockets use liquid nitrogen?
Rockets typically use Liquid oxygen and liquid hydrogen for fuel. I suspect this is what you are asking. I know of no rocket that uses liquid nitrogen.
What gas is used in rockets?
Other than rockets that use solid propellants or liquids (hydrazine, kerosene), large multi-stage rockets can be fueled with liquid hydrogen and liquid oxygen. The frigid liquid form is used because it provides a greater volume of propellant than simply pressurized gas. The more fuel it has, the faster and higher a rocket can go.
Why is helium for Pressurizing Liquid-Fuel Rockets?
Because helium will not mix with hydrogen and oxygen.
Does rockets use fossil fuels?
Yes, they use fossil fuels and they use liquid hydrogen and liquid oxygen.
Does oxygen only exist as gas?
No, in the rockets that NASA uses to launch vehicles into space they use liquid oxygen, as well as liquid hydrogen as rocket fuel.
Why is liquid nitrogen and oxygen transported as a liquid into space?
Liquid Oxygen and Liquid Hydrogen are used as rocket fuel as it is the most effecient way to thrust rockets into space, Liquid Nitrogen is not transported into space.
How do rockets off?
rockets take off when gases are shot out of the opposite direction with great force. The gases are conctrated by being forced through a small nozzle Liquid hydrogen and liquid oxygen is the fuel.
Which substance is a liquid fuel used in rocket engine?
Traditionally, rockets use cryogenic (super-cold) oxygen and hydrogen.
