Question

How Newton's Second law of motion is different from first law?

• A. Second law of motion, gives us a measure of the force
• B. Newton's first law of motion, gives us notion of external force
• C. Both
• D. None

Answer 1

The correct option is C Both

Newton's first law gives the qualitative effect of force i.e an object tends to remain in its initial state until no external force is applied to it whereas Newton's second law gives the method of measurement of force via $F=ma$.

Hence option C is correct.
