Question

What is more fundamental mass or weight?

Answer 1

1. Mass is the measure of the amount of matter in a body.
2. The SI unit of mass is $\mathrm{kg}$
3. Weight is the measure of the force of gravity acting on a body.
4. The SI unit of weight is $\mathrm{Newton}\left(\mathrm{N}\right)$
5. The equation relating the mass or weight of an object can be written as:
   $W=mg$
   Where, $W$ is the weight of the object, $m$ is the mass of the object, $g$ is the acceleration due to gravity.
6. The weight is derived from the fundamental quantity of mass.
7. Hence, mass is a more fundamental quantity than weight.
