Check wikipedia:
In modern scientific usage, however, weight and mass are fundamentally different quantities: mass is an intrinsic property of matter, whereas weight is a force that results from the action of gravity on matter: it measures how strongly gravity pulls on that matter.
So your weight on the moon is less albeit your mass is the same.


What is mass?
Mass is the m in [tex]F=m\cdot a[/tex]
And Mass is what causes gravity.

Mass is where the search ends, we haven't discovered some inner mechanism that produces it.
