Rockets stay in the air so long as they are burning enough fuel to overcome the acceleration of gravity. Let me explain. For something to leave the surface of a planet, in our case that planet would be the Earth, it must overcome gravity. Gravity on the earth has a constant acceleration about 9.8 m/s that points toward the center of mass of the earth, which is somewhere near it's core. Now to overcome that force a rocket must have an anti-parallel acceleration that is greater than that of gravity. A rocket achieves the necessary acceleration by burning fuel that provides propulsion. So long as the rocket is burning enough fuel to keep it's acceleration above that of gravity it will stay in the air.

Do rockets work better in space or in air?
Rockets generally work better in the space as compared on air. This is because there is no air resistance on the space.
How does a hot air balloon stay up?
it stays up because there is a fire inside of it and the gases from the fire focuses the hot air ballon to stay up
What do you think makes balloon stay up?
balloon stay up because of the air inside it. to make the balloon stay up the air should be light. inside the balloons you can find the air we called helium. helium is a light air that makes the balloon stay up. that's why if you blow the balloon it wont float because the air that comes from your mouth is not helium but carbon dioxide and carbon dioxide is heavier compared to helium so it wont float.
How do astronauts breathe in rockets?
Aliens give them air.
Why rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket accelerates in an opposite direction?
Rockets are convenient for space travel. Aircraft use the air to hold them up, but spacecraft travel beyond the Earth's atmosphere.
Why don't rockets need air to stay up?
This is a bit of a silly question. Rockets create thrust which a force which keeps up. They are not dependant on air to stay u
Do rockets work better in space or in air?
Rockets generally work better in the space as compared on air. This is because there is no air resistance on the space.
What is the difference between water rockets and modern rockets?
Water rockets use water and air modern rockets use thrust and oxygen.
What do model rockets do in the air?
explode
How does a hot air balloon stay up?
it stays up because there is a fire inside of it and the gases from the fire focuses the hot air ballon to stay up
Types of rockets animals go to outer space in?
my answer is air rockets because birds go in there
What is the force that enablesplanes to stay in the air?
air pressure. low pressure above wing high pressure below caused by shape of wing if air was thinner (no oxygen in atmosphere) planes would need rockets on them instead of jet engines
How are air planes and rockets different?
i do not now
Can a helicopter work in space?
No, only specially designed rockets can go up into space. As soon as a helicopter reaches our atmosphere boundaries, it would burn up. Rockets on the other hand, have been specially made to hold such extreme temperatures. :)
What is mean by air breathers?
Air breathers are engines that breath air as opposed to rockets which do not.
Why are planes and rockets pointed in shape?
To have less air resistance (in the case of rockets, while they are still in the atmosphere).
How long can jets stay in the air before they run out of fuel?
Jets stay up in the air because they feel like it!!! hohohohoh
