Using the law of conservation of energy (ESAHP) Mechanical energy is conserved (in the absence of friction). Therefore we can say that the sum of the E P and the E K anywhere during the motion must be equal to the sum of the the E P and the E K anywhere else in the motion. We can now apply this to the example of the suitcase on the cupboard View First-Law-of-Thermodynamics.ppt from CHEM PHYSICAL C at Colegio San Agustin-Bacolod.

For example, many appliances like washing machines are now labeled as energy efficient, or Energy Star, and use less energy than traditional appliances to complete the same task. If you can afford to upgrade to energy-efficient appliances, that's another great way to save money on energy costs, too Energy conservation techniques are effective because they encourage people to prevent waste while also saving money by lowering their utility bills and fuel prices. There are many ways to save energy , but the ultimate goal of conservation is to develop a system of sustainable energy that will help make energy cheaper and more abundant

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted Conservation of Energy. 8.01 Physics I, Fall 2003 Prof. Stanley Kowalski.
