Planck's constant times the frequency of a photon is equal to the value of this quantity for electrons plus the work function, according to the photoelectric effect. For ideal gases, it is equal to three halves times Boltzmann's constant times temperature. This quantity is not conserved in inelastic collisions, and can be written as momentum squared over 2 times mass. For 10 points, identify this quantity equal to one half times mass times velocity squared, which is poss

This quantity is not conserved in inelastic collisions, and can be written as momentum squared over 2 times mass. For 10 points, identify this quantity equal to one half times mass times velocity squared, which is possessed by an object by virtue of its motion.
