... Electric potential energy (Ue) is energy stored in the electric field. •Ue depends only on the location, not upon the path taken to get there (conservative force). Not a vector. •Ue = 0 at some reference point. •For two point particles take Ue = 0 at r = . kq1q2 •For the electric force U e r ...

... In the Einstein model for a solid, atoms are treated as one-dimensional quantum mechanical oscillators that can each accept an arbitrary number of energy units above the ground state. Recall that the multiplicity Ω(N, q) = (q + N − 1)!/(q!(N − 1)!) gives the number of states available to a system co ...
