is there friction at absolute zero?

Question

ok, i know this isn't possible. But let's say, hypothetically, i have a marble that is at absolute zero, and it's sliding across a slab of ice that is absolute zero. would there ever be any friction caused?

Answer 1

But if the box is moving kinetic energy will be released as heat and hence you will not be at absolute zero any more.

Answer 2

"OK, I know this isn't possible . . . " But how do we analyze the possibility of something impossible? In absolute zero, there would be no movement at all, so the marble could not slide across the slab of ice. There would be no friction because there would be no movement. Absolute zero is really nothing at all: no heat, no movement, no nothin' at all. And since matter is just sticky energy, it might be argued that there would not even be any matter. If there is no energy, is there any matter?

Answer 3

Your question contradicts itself. Kinetic energy (motion) creates heat; if either the marble or the slab of ice are moving then you can't be at absolute zero.

Now we assume that the marble and slab of ice are very close to absolute zero then yes their would be miniscule friction (I.E. kinetic energy lost due to physical interaction.)

Answer 4

Technically, all molecular activity would cease at absolute zero, so if there were a marble at that temperature, its molecular properties would be vastly different than we would imagine marbles at room temperature. Furthermore, as far as I know, only very small groupings of molecules have come close to achieving absolute zero. Solid elements in any larger proportions would not reach such a low temperature as easily because by virtue of their molecular density, there would be friction that would act against it.

Answer 5

in absolute zero there is a mass.

the superconductors have mass and all the experiments are carried out as close as possible to absolute zero.


friction depends on the frictrion coefficient and the weight.

now

since it is a hypothetical question it would certainly be less than in normal circumstances. almost zero .
lwo temperature are said to stop atoms from vibrating. it is never said that movement is not allowed

Answer 6

Look up 'condensate physics.' They can cool things cold enough (but not exactly absolute 0) that a group of atoms behave as though they're one giant atom. You can get things like superfluid which has 0 viscosity. Supersolids also can be created.

Answer 7

Absolute zero means lack of motion.

If you make a motion, temperature rises and yon can't maintain absolute zero

Answer 8

no there is zero energy at absolute zero

Answer 9

Absolutely there is!
