While this is true, it can be wasted. I am thinking specifically of the energy used to condition (heat or cool) a room. Everyone thinks, “Heat rises.” While heat can rise, it doesn’t have to. Heat is lazy.

Energy cannot be created or destroyed….but it can be wasted

WebThe law of conservation of energy states that energy can neither be created nor destroyed – only converted from one form of energy to another.

WebYes, all machines waste energy. Car alternators are typically 50% efficient as they use current to produce the magnetic field instead of a permanent magnet. This means you have to put into 2x as much mechanical energy as you get out in electricity. WebIn your thought experiment, all observers agree that the electron and positron are destroyed and a photon is created. Likewise, it seems to me, the (genuine) creation or destruction of energy (if that is possible) must be absolute, i.e., observer independent. But kinetic energy is observer dependent.

WebConservation of energy applies only to isolated systems. A ball rolling across a rough floor will not obey the law of conservation of energy because it is not isolated from the floor. The floor is, in fact, doing work on the ball through friction. However, if we consider the ball and floor together, then conservation of energy will apply.
