No shit. And measuring the mass of the slug in question involves weighing it. Or do you have another method involved for determining the mass of an object used as the constant for measuring mass?
Wow. Just....wow. So *this* is what modern education has come to?
Seriously, weight is an accelerational effect upon the mass by a force, in this case, gravity. Einstein taught us that any acceleration, outside of a frame of reference, would be identical. So, providing an acceleration by means of some other force while in microgravity would accomplish the same thing.
I suggest that you do a quick Google search on the subject. In about 5 seconds I found articles on using springs on the ISS, and a patent application for using a centrifuge to accomplish the same thing.
