Definition of zero-point energy in English English dictionary
zero-point energy: The lowest possible energy of any quantum mechanical system; a consequence of the uncertainty principle
zero-point energy: The energy possessed by something at a temperature of absolute zero
zero-point energy: Vibrational energy retained by molecules even at a temperature of absolute zero. Since temperature is a measure of the intensity of molecular motion, molecules would be expected to come to rest at absolute zero. However, if molecular motion were to cease altogether, the atoms would each have a precisely known location and velocity (zero), and the uncertainty principle states that this cannot occur, since precise values of both position and velocity of an object cannot be known simultaneously. Thus, even molecules at absolute zero must have some zero-point energy
