Question

The rocket works on the principle of conservation of:

• A. linear momentum
• B. energy
• C. velocity
• D. mass

Answer 1

The correct option is A linear momentum

Rocket works on the principle of conservation of momentum. Rocket ejaculates gases in backward direction which creates momentum of the gases backwards and thus by conservation of momentum, the rocket gets momentum in the forward direction making it move forward.
Thus the rocket works on the principle of conservation of linear momentum.
