Shaking a feather in an airless environment would present visually like shaking a stiff rubber model of a feather - there would be no air to provide resistance. Moving the shaft would move all parts of the feather in unison, something we would see on Earth only in a breeze.
Joe: the mass of 1 earth lb of feathers = the mass of 1 earth lb of hammers, wherever you take them. However, even 1 oz of feathers would still hit the ground at the same time as 1 lb of hammers. Its not the weight difference on the moon but the lack of air that's relevant.
I still think a pound of feathers is heavier than a pound of hammers, but only if you're on the moon ;-)
ReplyDeleteDid anyone else see that feather move at 0:21?
ReplyDeleteI believe we really did land on the moon but what could have caused this?
He's holding it with his fingers; he must have moved the glove along the shaft of the feather.
