Answer:

Explanation:
Mass:
- The quantity of matter in an object in called mass.
- Mass is a constant quantity.
Weight:
- The gravitational pull on an object is called weight.
- Weight changes.
Relation:
We know that,
W = mg
Since mass is a constant quantity, it does not change. But, weight depends upon the gravity of any planet or atmosphere and changes accordingly. That is why weight and mass can never be the same unless g = 1.
