how do rockets move in space if theyre is no oxygen?

Question

A rocket engine works becouse it sends particles moving very fast out of it and those particles push against particles in the atmosphere and propel the rocket forward, but in space there are no particles there is only a vacuum so what propels the rocket ??

Answer 1

First, the rocket can operate in space because it carries its oxygen with it, either as liquid oxygen or as part of a solid propellant fuel.

Second, the rocket isn't pushing against the atmosphere. Study Newton's laws of motion and conservation of momentum. If you are standing on skates and throw a heavy ball, you acquire as much momentum backward as the ball acquires forward.

Answer 2

The typical rocket engine uses hydrogen and oxygen gas. When combined and ignited they will form water and a huge explosion.

The super hot water particles are expelled out of the rocket nozzle into empty space. The particles will then push off on the particles released earlier, and more particles will push off on those particles and so on and so on.

You don't need an atmosphere of gas to move with a rocket engine.

In fact, it is way faster than on earth because there is no air resistance to slow down the rocket.

Answer 3

A rocket would not "push against something" to go. Neither does a jet engine, or a jet ski. The propulsion of a rocket is predicated on the utility of Newton's third regulation of Gravity - each and every action has an equivalent yet opposite reaction. in straight forward terms, a stress performing in one course produces a reaction of the comparable volume in the different course. So contained in relation to a rocket, while the gasoline is burned the stress of the warm gasses escaping interior the process the rocket's exhaust creates an equivalent stress performing interior the alternative course. If the gasses get away to the rear, the reaction stress acts interior the forward course and the rocket strikes forwards. that's the comparable action that motives weapons to balk while fired - as a bullet leaves the gun, the stress of the bullet creates an equivalent stress performing interior the alternative course and that's felt as a balk.

Answer 4

Rocket thrust results from the high speed ejection of material and does not require any air or other medium to "push against". Conservation of momentum says that if material is ejected backward, the forward momentum of the remaining rocket must increase since an isolated system cannot change its net momentum.

Answer 5

In physics we studied the "Rocket Equation" which can do alot of cool things, but in this case it applies as well... the basic idea is that because of the theory of the conservation of momentum, by expelling a part of its mass at high speed in one direction, a rocket can accelerate itself the other direction... hope that helps

Answer 6

no no no. Its Newtons Law at work. For every reaction (the combustion forcing stuff out in one direction), there is an equal reaction in the opposite direction - the direction the rocket is moving.

Answer 7

Once the rocket breaks free from gravity,
there is no Resistance to prevent it from
moving on.

Also, space is not a vacuum.
Black holes are a vacuum.

Answer 8

The actual combustion happens inside the rocket. What is expelled is the products of such reactions.

Answer 9

Liquid Oxygen is in the rocket.
