Which of Newton's laws of motion gives the definition of force as well as inertia?
ASecond law
BThird law
CLaw of gravitation
DFirst law
Answer & Solution
Correct answer: D. First law
1. Newton's first law states a body stays at rest or in uniform motion unless an external force acts.
2. The property to resist change (inertia) follows directly from this.
3. The need for a force to change that state defines force, so the first law gives both definitions.
