WebThe second experiment tested the actual conservation of energy by comparing the spring potential energy to the converted kinetic energy of the cart at the photogate. The third experiment essentially tested the same conservation law from the second experiment, but with the cart traveling up various inclines as opposed to a zero degree angle launch. In 1918 it was proved that the law of conservation of energy is the direct mathematical consequence of the translational symmetry of the quantity conjugate to energy, namely time. That is, energy is conserved because the laws of physics do not distinguish between different moments of time (see Noether's theorem). During a 1961 lecture for undergraduate students at the California Institute of Technology, Richar…
