Question

Which of the following laws represents the qualitative measure of force?

• A. Newton's first law of motion
• B. Fleming's right hand rule
• C. Fleming's left hand rule
• D. Zeroth law of thermodynamics

Answer 1

The correct option is A Newton's first law of motion

Newton's first law of motion represents the qualitative measure of force.It states that:

An object remains in the state of rest or of uniform motion in a straight line unless compelled to change that state by an applied unbalanced force.

All objects resist change in their state of motion. The tendency of undisturbed objects to stay at rest or to keep moving with the same velocity is called inertia. This is why, the first law of motion is also known as the law of inertia.
