The most common answer to the above question is — hot jet of gas comes out of the nozzle of the rocket engine at high speeds and as a reaction the rocket moves (is propelled) in the opposite direction . But is this answer right? Let us explore what goes on inside a rocket engine and arrive at the right answer.
