JEE Advance - Physics (1980 - No. 2)
A rocket moves forward by pushing the surrounding air backwards.
TRUE
FALSE
Explanation
Explanation :
A rocket's propulsion in space (and even in the atmosphere) does not depend on pushing against the surrounding air. Instead, it relies on Newton's third law of motion: every action has an equal and opposite reaction. By expelling hot gases (the exhaust) at high speed out of its nozzle, the rocket produces a forward thrust. This mechanism works in the vacuum of space just as well as in an atmosphere, proving that it does not depend on air.
