A rocket does not need air to “push against.” Exhaust gases are thrown backward at high speed; by Newton’s third law, the rocket is pushed forward. This works in space where there is almost no air.

Thrust depends on how much mass is ejected and how fast it leaves. Steering often means directing that exhaust. Air is useful for fins on some rockets in atmosphere, but it is not the source of the forward force.

Physics students with tutors in Gulberg can contrast a rocket with a car (wheels push the road) to lock in the action–reaction idea.
