Question

Explain the principal on which the lunching of a rocket is based

Answer 1

Answer:

the launching of rocket is based on the third law of motion. the third law is: to every action there is an equal and opposite reaction

Answer 2

Rocket launching is based on Newton's third law of motion.

In a rocket, fuel is burnt inside the rocket and the burnt gases at high pressure+temperature are expelled through a nozzle.

Thus, a rocket exerts a force on gases to expel them through nozzle backwards and the outgoing gases exert an equal and opposite force on the rocket due to which it moves in the forward direction.
