A rocket works on the principle of conservation of which physical quantity?
- A.Mass
- B.Energy
- C.Linear momentum
- D.Angular momentum
Show correct answer & step-by-step solution
Correct answer: C — Linear momentum
Solution
A rocket expels gas at high velocity in one direction, which creates an equal and opposite reaction force on the rocket. This is a direct application of the law of conservation of linear momentum.
