Some students were conducting an experiment where they were measuring the energy of a ball as it rolled down a ramp. According to their calculations, the total energy decreased. Which statement is the best explanation for this loss of energy? The missing energy was destroyed. The missing energy was lost as heat due to friction. The students conducted their measurements incorrectly; the energy totals should have been the same. The total amount of energy always decreases as it is converted from one type of energy to the next and is to be expected.
