Gareth56 Posted December 10, 2008 Posted December 10, 2008 Is a 1 Newton of gold worth more on the Moon than on Earth?
Phi for All Posted December 11, 2008 Posted December 11, 2008 If its Moon to Earth rarity exceeds its Moon to Earth weight due to gravitational acceleration difference and you can find a buyer, I would say yes.
Cap'n Refsmmat Posted December 11, 2008 Posted December 11, 2008 Think about it. If you hung a bunch of gold from a spring scale on the moon (where gravity is weaker and doesn't pull as hard), would you need more or less gold to make the scale read "1N" compared to being on the moon?

If you hung a bunch of gold from a spring scale on the moon (where gravity is weaker and doesn't pull as hard), would you need more or less gold to make the scale read "1N" compared to being on the moon? Using the equation weight(N) = mass x accel. due to gravity yields the following (I hope) Moon 1N/1.6m/s^2 = 0.625kg Earth 1N/9.81m/s^2 = 0.102kg So it looks like to requires more gold on the Moon! Thanks:-)
DrP Posted December 11, 2008 Posted December 11, 2008 I'm thinking along the same lines as Phi here though. On earth, obviously the 0.625kg lump will sell for alot more. But I would rather own 0.102kg of gold here on earth than have to deal with the delivery cost of transporting your 0.625kg from the moon. I don't think it is supposed to be a trick question though.
Tom Vose Posted December 20, 2008 Posted December 20, 2008 But one Newton of gold... its not really that much
Phi for All Posted December 20, 2008 Posted December 20, 2008 But one Newton of gold... its not really that much Relative to what?
thedarkshade Posted December 20, 2008 Posted December 20, 2008 I assume there a simple answer to this: [math]Q=mg[/math] [math]m=\frac{Q}{g}[/math] A decrease in gravitational acceleration means an increase in the mass (as long as we have Q constant which is our case), so I guess its worth more on Moon!
Tom Vose Posted December 20, 2008 Posted December 20, 2008 Relative to what? Well, i remember reading recently, that if you could collect all the gold in the world, it would only be enough to fill three entire football stadiums. A Newton has about the same weight as a Granny Smith Apple, and that would be like a nugget on a good day in the American Rocky Mountains.
Klaynos Posted December 21, 2008 Posted December 21, 2008 But one Newton of gold... its not really that much I wouldn't say no to it....
MolecularEnergy Posted December 21, 2008 Posted December 21, 2008 I wouldn't say no to it.... Neither would I.

An objection which has squat to do with the premise of the question posed in the OP. And if you *are* talking about value, as DrP points out, 0.625kg is quite a bit when you have to factor it as part of the payload of a Moon trip.
