Hi PF users, The subject of this thread is clearly stated on the title ( above). So my question is what is mean't by a 'potential well'. I have a question based on Lennard jones potential from where this question arose in the first place ( which I will probably post on respective sub-forum if I get stumped). My current understanding is from ( google) , someone correct me if I am mistaken but when the terms 'local minimum' are used in the context of potential well .. does it strictly imply that at this energy depth , we can't have any transition say e.g P.E into kinetic energy as it would tend to in nature (entropy). Can someone elaborate on this.. I ask this because I have a question which's based on LJ potential equation. Thank you.
