Inertia is depends upon only?
Correct answer: C. Mass
- A. Velocity
- B. Direction
- C. Mass
- D. Time
Explanation
Inertia depends only on mass: a greater mass requires a greater force to produce the same change in motion. Velocity, direction and time do not determine the amount of inertia. The likely mistake is choosing velocity because inertia is noticed when an object's velocity changes, but the resistance comes from its mass.

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.
