Newton's first law of motion gives the concept of _________?
Correct answer: C. Inertia
- A. Energy
- B. Work
- C. Inertia
- D. Momentum
Explanation
Newton's first law states that an object remains at rest or in uniform straight-line motion unless an unbalanced external force acts on it. This resistance to a change in motion is called inertia. Students may choose momentum because it is related to motion, but momentum is not the concept directly defined by the first law.

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.
