We have two bodies, One is moving with 2m/s velocity and other is at rest, which one has greater inertia?
Correct answer: D. Both have same inertia because inertia depends upon mass only
- A. Moving body
- B. Body is at rest
- C. Both have not any inertia
- D. Both have same inertia because inertia depends upon mass only
Explanation
Inertia is the resistance of a body to a change in its state of motion, and it depends on mass rather than whether the body is moving or at rest. Therefore, if the two bodies have equal mass, they have equal inertia regardless of one moving at 2 m/s and the other being at rest. The likely mistake is choosing the moving body because motion is being confused with inertia.

About Newton's Laws of Motion
Newton’s laws explain inertia, the relation between net force and acceleration, and action-reaction pairs. Questions involve free-body diagrams, balanced and unbalanced forces, F = ma, force as the rate of change of momentum, and identifying genuine third-law pairs, which act on different bodies.
