Not mass, surely, but they are exactly how friction is indicated, aren't they?

So how do you determine friction if not with static UW/DW comparisons?
Forgive me if this has already been addressed elsewhere, but I'm a little
out of touch here under my (hot, cold, or wet) rock in South Central Kansas.

Ok, so how do you differentiate between a friction and a mass problem?
