Question

The unit of mass is kilogram, while that of weight is Newton. Explain.

Answer 1

1. Mass is a fundamental quantity.
2. It is a measure of the amount of matter contained in an object.
3. Therefore its unit is Kilogram $\left(kg\right)$.
4. Whereas, Weight is a force.
5. The weight of any object is the force of gravity with which the earth pulls any object towards its centre.
6. This is the reason why objects fall down when they are thrown up.
7. Since, weight is a force, its unit is Newton $\left(N\right)$.

Thus, The unit of mass is kilogram, while that of weight is Newton.
