Force and Energy?

[Boris Lagutin]

There is a mass. If the mass's acceleration is caused by some force it is clear. But what if the mass's acceleration is caused by NOT A FORCE as it happens in "Ehrenberg-Siday-Aharonov-Bohm effect" (if I understand this effect right)? May it violate the conception of Energy? Here is a link to the article about this effect:

Thanks a lot.

Position, velocity and acceleration of particles are all classical concepts that do not simply correspond to the properties of very small things. An electron does not travel around a nucleus (if it did, it would be accelerating* towards the nucleus (centripetal acceleration) and therefore would radiate EM waves). A photon does not 'travel through' two slits+. And, on the quantum mechanical scale and over short timescales, energy is not precisely conserved, which is demonstrated by quantum tunneling.

I realise that this is only a general rather than a specific answer, but I'm afraid I know only a little about this effect.
