Question

We say that 50kg is ​​​​​​my Weight ​​​​​​but what it is actually ,my weight or my mass(PLEASE EXPLAIN)?

Answer 1

Technically speaking, weighing machines should measure your weight, which is the force of attraction due to gravity between you and the Earth. In common everyday usage Kg is used as a measure of weight. However, if you use the formal SI definition as used by physicists, then Kg is a unit of mass, not of weight (force).


Therefore what weighing machine calculate is the weight of the body which depends on gravitational constant.But mass is a constant .
