Is There Any Motion at Absolute Zero?

AI Thread Summary
Motion can exist at absolute zero, as 0 Kelvin represents the minimum energy state rather than a complete absence of energy. Subatomic particles remain in their lowest energy states, which still allows for some motion due to quantum effects. The uncertainty principle plays a role in this phenomenon, indicating that particles cannot be completely at rest. While an object at absolute zero can be physically moved, its internal particle motion is governed by zero point energy. Thus, motion at absolute zero is a complex interplay of quantum mechanics and thermodynamics.

Is it possible for motion to exist at 0 Kelvin?
 
Physics news on Phys.org
Yes, absolute zero is the MINIMUM energy state for an object, not a ZERO energy state. The subatomic particles would all be in their lowest energy states, but for some that state would still entail some motion I believe. I'm sure the uncertainty principle matters here somehow.

Well, if I had an object at 0 Kelvin (strictly speaking, some non-zero temperature that is very close to zero) I could still move it around my lab... So the answer has to be yes.

If you were asking about internal movement of the particles making up the object, then Drakkith has already answered.
 
zero point energy.
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
