I had a thought-experiment I was pondering the other day. If you could somehow isolate a single atom inside a vacuum inside a Faraday cage, how would that atom behave in terms of translational movement?
Objects in vacuum push do not push against anything. They move inertially in a straight line until they meet a resistance.But there's nothing to "push" against? It's all alone and doesn't have the nearby interactions of other atoms to make its own vibrations "count" so to speak. Or at least this is my question.
(a la similar to one trying to run on ice)
Every time the atom bounces off the wall there is the possibility of energy transfer from the atom to the wall or from the wall to the atom. If the wall is kept at absolute zero then the atom will eventually transfer all of its energy to the wall and settle onto the floor. It not the atoms of the wall and the atom in the tank will maintain the same average temperature.Yes, but if its energy to "bounce" is from its initial kinetic energy when you got it in there, how does it keep bouncing? Wouldn't this energy eventually run out/not be useable for the same kind of movement?
I was assuming as stated earlier that when it "bounced" some of that energy would be transferred.Your posts seem to suggest (sorry if I misinterpreted) that you think an object needs to be constantly supplied with energy to stay in motion. This is untrue. An object in motion will stay in uniform motion unless acted on by an external force. This is Newton's first law.
It would indeed follow an arc, but you cannot discount the initial energy it had. You also cannot ignore what the walls are made of and what temperature they are at.I was assuming as stated earlier that when it "bounced" some of that energy would be transferred.
Really though what I was interested in was if gravity could pull it to the bottom.
