Per NCERT, how does a ROCKET launch into space?
AThe rocket simply falls upward
BThe rocket engine ejects gas DOWNWARD; the gas exerts an equal and opposite UPWARD force on the rocket (Newton's Third Law) — lifting it off
CAir pushes it up from below
DThe rocket pulls itself up by ropes
Answer & Solution
Correct answer: B. The rocket engine ejects gas DOWNWARD; the gas exerts an equal and opposite UPWARD force on the rocket (Newton's Third Law) — lifting it off
Per NCERT §6.6, rocket propulsion = Newton's Third Law (exhaust down, rocket up). The other options misstate.
