12.1 Work Energy Power
... Energy can change from one form to another. Eventually all forms of energy change into heat which is lost to space. 4.18 J of any energy (work) will become 1 cal of heat (the amount of heat that raises the temperature of 1 g of water 1 celsius degree). Conservation of energy means that energy can no ...
