How many folk get this right me wonders, and how many fall into either the simple or the none too obivous trap?

If the pounds are pound-mass then the feathers will usually be lighter in weight (because they have lower density, buoyancy and all). Usually you don't want to give this answer in physics multiple choice questions though.

Which is the none-too-obvious one?

If I hit you in the face with a pound of feathers, you'll feel less pain then if hit with a pound of gold

A pound is a pound. The pound of feathers will just be bigger than the pound of gold, simply because feathers have less mass so you'd have to compress them big time to get to the size of gold and keep the same weight.

Hate to tell you but we have two wrong answers so far!

Yes you can ignore air pressure, mass of air and buoyancy, but a subtle, no damn it very hard to spot error has crept into folks thinking here. The answer is likely to surprise, enlighten and possibly annoy you.

Before anyone ponders - no, it isn't some warped joke or anti-gravity theory...

Meh, word play ... once things get into semantics there is no right answer.

Rather than keep you stewing I'll short circuit this and at least let you know the correct answer - see who can figure it out first...

Feathers is heavier - for none of the reasons discussed here so far.

uhm... enlighten us...?

I agree with Mfa, once you start arguing semantics, there is no correct answer.

g__day, you posted this in another board:

As i said, semantics...

A pound of something will be the same as a pound of something else. If not, one of them is not a pound.

Once you start with weighting conventions people made, it's semantics and social differences. In physics, a pound or a kilo or whatever of something will weight the same as a pound or kilo of something else.

Actually the standards, not the meaning of words - so semantics is not the correct answer, standards are.

Yes surprise surprise precious metals are still weight in troy ounces and pounds - which are lighter than common ounces and pounds.

Wonders never cease huh?

It's easy, the gold has a different measure (1 pound = 31,1035 g), as opposed to Avoirdupois Weight of 1 pound = 453,59237 or Troy Pound which has 373,2417216 g.

Thanx Wikipedia

The whole thing hinges on the semantic duality of the word "pound".

I don't like pounds.

What's heavier 1kg of apples or 1 kg of oranges?
NOTE: W = m*g.

W/apples = 1 * 9.8 = 9.8N
W/oranges = 1 * 9.8 = 9.8N

Standards are contextual, only valid between those who agree to use them. This isn't even a formal standard though, just a convention.

The meaning of words is defined by majority rule.
