Well rockets don't push off anything it's the force of substances leaving it at a rapid rate and according to sir Isaac Newton, with ever reaction there is an equal and opposite reaction. Like for example you can think of the recoil of a gun. It's the force of the blast of the bullet that wants to send the glock flying out of your hand, it's not from pushing off the air
Yea and exactly what @creativedragonbaby said because of newtons other law, which is that an object in motion will stay in motion unless acted upon with an unbalanced force, which is a complicated way of saying that if you are like in space and you throw a baseball into infinity it will never stop
it pushes off its own fuel (or in some cases its technically called a propellant like with ion thrusters where the energy doesn't come from the "fuel").
Rocket fuel ignites to produce expanding gases, which are then vented through narrow "nozzles" created for the purpose of directing their release. Newton's third law, action having reaction, is a statement that action is doubled. If you sit in a chair, you exert force down amd the chair exerts force back up at you. A and B always interact, there is no one single actor. By definition, when the gas exerts pressure on the rocket as it escapes, the rocket material exerts an opposite pressure on the fuel. In layman's terms, "it pushes off it's own fuel" is correct.
Well it depends oh what you're using. If they are making minor adjustments using SAS then it's the force of the air leaving.
If they are blasting through space then it's the force generated by the burning fuel. Essentially pushing off of heat in a deathly cold place, though in it's entirety it is WAY more complex than that. But this if for the simpletons, should one ever see it.
God almighty, there's some blazing bloody imbeciles on this site! Perhaps if they were to actually STUDY Newton's Third Law, instead of spending their school time updating social media like little pansy compliant "consumers"!
So guest, you've used up your three comments.
Allow me to say, shut up.
Not everyone has the 3rd law memorized. And better yet, not everyone has the drive to prove others wrong like you do.
And I'll be damned if the only thing acting on that ship is Newton's Third Law. The universe is far too complex to be narrowed down to a simple, "recoil".
So here's a bit of advice, don't act cocky unless you're alright with being shot down later.
Because you WILL be shot down. That's how science works. Ever growing, ever changing. And don't call people, "...blazing bloody imbeciles..." because they took a guess.
You want people to study science? The quickest turn away is words like those.
Correct! Newton's first law is also at work. A vacuum has no friction, so once propelled a rocket's engine can be turned off and it will continue to move until acted upon by an outside force (gravity, asteroids, opposite aimed thrusters, etc).
A simple way of saying it is the rocket pushes off of itself
