Question

What law does the 'Rocket' works on?
1. Newton’s Second Law
2. Newton’s Third Law
3. Newton’s First Law
4. Archimedes Law

Answer 1

Correct Answer - Option 2 : Newton’s Third Law

The Correct Answer is Newton’s Third Law.

• Newton's third law- If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. 
• This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself. 

• Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. The acceleration of an object depends on two things, force and mass.
• Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This postulate is known as the Law of Inertia.
• Archimedes' law states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. Archimedes' principle is a law of physics fundamental to fluid mechanics. It was formulated by Archimedes of Syracuse.
