In the virial theorem the numerical value of the average potential energy within a system is exactly twice that of the average kinetic energy. I know the theorem is proved mathematically but to me it seems a coincidence that one value is exactly twice the other value. I find that interesting.(adsbygoogle = window.adsbygoogle || []).push({});

I find it more interesting and more of a coincidence when I take into account the fact that the potential energy term is not an absolute value but the value it would have if the potential energy at the chosen separation of infinity is given the chosen value of zero.

Can anyone explain, without the maths, why one value is twice the other. I'm trying to get an intuitive feeling of why this should be the case.

Also, does the Schrodinger analysis of the hydrogen atom give a better proof of the virial theorem than the Bohr treatment? I ask this because I think the simple Bohr analysis ignores the kinetic energy of the proton.
