full_question: A correction functional for calculating this quantity equals the dot product of two gradients of a probabilityfunction, over eight times the probability, and is named for von WeizsÃ¤cker. This quantity increases with thecurvature of a wavefunction since its operator is proportional to del-squared. Relativistically, this quantityequals m times c squared, times the Lorentz factor minus one. The maximum amount of this quantity equalsh-nu minus the workfunction in measurements of the photoelectric effect. Escape velocity is derived bysetting big G times two masses over the planetary radius equal to it. It is conserved for elastic collisions, butnot for inelastic collisions. For 10 points, name this quantity equal to half the mass times velocity squared.
