I understand Rocket works on Newton's 3rd law. So there has to be action-reaction pair acting on two different bodies. I know rockets accelerate in space, where there is nothing. So now I want to know those action reaction pair that keeps the rocket accelerating.
Specifically I want to know which part of the rocket (which physical component/structure/fuels/gases? ) is giving action on which other part/components (this part cannot be air, since it is in space) and in turn which other part is giving reaction and on which part of rocket?
I am trying to identify this pair. Please help me.
Thanks
