NEET Physics Newton's Laws MCQ Question

Type: MCQ-conceptual-Hard-Class 11

Which of the following combinations correctly describe Newton's laws of motion?

A

The first law defines inertia, the second law relates force and acceleration, and the third law states that for every action, there is an equal and opposite reaction.

B

The first law applies only to moving bodies, the second law states that all forces are equal, and the third law applies to frictional forces only.

C

The first law states that forces are required for motion, the second law defines momentum, and the third law applies only in a vacuum.

D

The first law describes uniform motion, the second law states that force is independent of mass, and the third law is related to gravity only.

Correct Answer

Option A

Detailed Explanation

Option A accurately describes the first law as defining inertia, the second law relating force to acceleration, and the third law addressing action and reaction pairs. This aligns with the foundational principles established by Isaac Newton.
