hackin_n_bashin Posted November 27, 2009 Share Posted November 27, 2009 It's not really to do with gravity, it's the fact that under free fall conditions buoyancy is removed from the equation, so the cork stays where it originally was Quote Link to comment Share on other sites More sharing options...

Homer Posted November 27, 2009 Share Posted November 27, 2009 Not read the replies yet, but I think the cork will stay where it since all objects in the bucket will be under zero gravity. Quote Link to comment Share on other sites More sharing options...
Jas Posted December 4, 2009 Share Posted December 4, 2009 Ive just tried it... the answer is a broken bucket a wet floor and I cant find the cork.. only kidding.. is the answer the universe implodes as god forgot to think that particular scenario through leaving the the words "Game Over!" eternally hanging in 'nothingness'?? Only kidding again... The cork, the bucket and water all fall at the same rate. There relative positions remain theoretically stable as gravity acts independently on each object of mass in exactly the same way. Quote Link to comment Share on other sites More sharing options...
Jake Posted December 4, 2009 Share Posted December 4, 2009 The reason a cork floats is because it has air in itNot really. A scuba diver's air tank doesn't float. Isn't it the average density of the object compared to the density of an equal volume of water, that affects whether something floats? (In normal conditions I mean) Quote Link to comment Share on other sites More sharing options...
colsoop Posted December 4, 2009 Share Posted December 4, 2009 I had a similar question a few years back and seem to remember that part of the answer was to do with all the objects being weightless. Quote Link to comment Share on other sites More sharing options...

pedrosixfour Posted December 4, 2009 Share Posted December 4, 2009 The cork would stay at the bottom as the density difference, which would make the cork float under normal conditions, no longer applies as all items are now effectively weightless and therefore without density.

Tricky-Ricky Posted December 4, 2009 Share Posted December 4, 2009 Bit irrelevant really as in a zero G situation the water wouldn't stay in the bucket so there is no predicting where the cork would end up;) Quote Link to comment Share on other sites More sharing options...

Matt H Posted December 4, 2009 Share Posted December 4, 2009 I think it will not float up as the water only pushes the cork up because it is heavier than it under gravity. As things that are in 'free fall' are supposed to be weightless, there is no differencial between the two materials. That's my take on it, but I think we need someone to throw a bucket of water and cork out of their 25th floor apartment to make sure Quote Link to comment Share on other sites More sharing options...

Matt H Posted December 4, 2009 Share Posted December 4, 2009 This whole topic reminds me of the hammer and feather drop that was undertaken on the moon. Obviously different physics because this test involved atmospheric pressure, but a astronaut dropped and hammer and feather at the same time and they landed at the same time Quote Link to comment Share on other sites More sharing options...

tbourner Posted December 4, 2009 Share Posted December 4, 2009 So if there was wind resistance would it just rise slower in the water? Quote Link to comment Share on other sites More sharing options...
Matt H Posted December 4, 2009 Share Posted December 4, 2009 So if there was wind resistance would it just rise slower in the water? There couldn't be as the when the bucket falls it accelerates at it's maximum and therefore becomes weightless in its free fall state.
