Question : Rocket works on the principle of:
Option 1: Newton's third law
Option 2: Newton's first law
Option 3: Newton's second law
Option 4: Archimedes Principle
Correct Answer: Newton's third law
Solution : The correct option is Newton's third law.
Newton's third law of motion, which states that there is an equal and opposite reaction to every action, is the foundation upon which rockets operate. This means that a rocket encounters a force in the opposite direction from the direction in which it expels mass (the action), propelling it forward (the reaction). This is accomplished in a rocket engine by the high-speed exhaust gases being expelled through a nozzle at the back of the rocket.
