The launching of a rocket is based on Newton’s third law of motion.

Answer»
  • Newton’s third law of motion states that ‘Every action force has an equal and opposite reaction force which acts simultaneously.’ 
  • When the fuel in a rocket is ignited, it bums as a result of chemical reaction. 
  • The exhaust gases escape with a great force in the backward direction. 
  • It exerts an equal and opposite reaction force on the rocket, due to which the rocket moves in the forward direction. 
  • Thus, the principle of launching of rocket is based on Newton’s third law of motion.
