    In light of the recent "feather" discussion, I'm almost afraid to be the first one to post.
    Doh!!!

    no, gold is measured in troy weight=12 ounces a pound, feathers are measured in regular 16 oz.=1 pound

    Yes, but he should have specified that in his first post. a pound = a pound, unless you specify which one.

    youre the loser. Using imperial units make you it. Use SI units in science or don't use units at all

    Which has the most mass?

    1) A ton of gold

    2) A ton of feathers (weighed seperately)

    3) A ton of feathers (weighed together).

    That is using the same set of scales in the same lace to weigh each.

    When you weigh the feathers (individualy) the COG will be lower than when weighed together, therefore the gravity experienced will be slightly different.

    dont shoot me down in flames or nothing, but i thought mass was independant of gravity and when gravity is involved it becomes weight

    Actually, you are right captain.
    Doh!

    But billco's post is clever if you replace 'mass' with 'weight.'

    cheers.
