Which conservation principle is applicable in the case of the motion of a rocket?

A Conservation of mass
B Conservation of charge
C Conservation of momentum
D Conservation of energy

Correct Answer: Conservation of 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 a momentum in the forward direction making it to move forward.
