(the total energy divided by the cavity volume L3) can be computed using the energy equipartition theorem, which associates a kinetic energy (Ec) of Kb T/2 per degree of freedom:
The difference between the dynamics of electrons and nuclei is derived in the following way: (i) the nuclei are typically tens of thousands times heavier than the electrons; (ii) the particles constituting the molecules are in equilibrium, so, on aver- age, they have similar kinetic energies (equipartition theorem); (iii) thus, the ratio of the square of their velocities (electrons and nuclei) will be roughly the inverse ratio of their masses (velocity ratio on the order of hundreds); (iv) then the wave- length associated with the nuclei is hundreds of times lower than the one corre- sponding to the electrons.
where T represents the kinetic energy operator, V the external potential operator (the one created by the nuclei) and G the inter-electron repulsions potential.
This fact implies different Hamiltonians that only differ due to the difference in the external potentials because the kinetic energy part and the one corresponding to the inter-electron interactions are the same as soon as the number of

First, it will be shown that a discontinuity in a wave function would result in a non- physical infinite contribution to the expectation value of the particle's kinetic energy, T .
consider the contribution to the expectation value of kinetic energy in the limit x x0.
Hence, we conclude that the contribution to the expectation value of kinetic energy due
The infinite contribution to kinetic energy comes from the infinite slope of the wave function.
Assuming that our real wave function is continuous, we now show that a discontinuity in the spatial derivative of the wave function makes a finite contribution to the expec- tation value of kinetic energy.

They will have more energy than that if they are moving, for then in addition to their rest energy they will have energy of motion or "kinetic energy."
The kinetic energy they thus obtain comes from the electric field.
Let us suppose that to compensate this they have kinetic energy, i.e.
But how can the particles have negative kinetic energy?
Classically, the smallest amount of kinetic energy that something can have is zero-when it is not moving.

The energy E generally includes internal energy U, kinetic energy KE, and potential energy PE terms, as follows:
where m˙ is mass flow rate and h^ is total specific energy, equal to the sum of spe- cific enthalpy, kinetic energy, and potential energy, that is, h^ 1/4 h + V2=2+ gZ.
