If energy can neither be created nor destroyed, then how can it be wasted?

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. Web26 de jan. de 2024 · 4. The short answer is no. Energy didn't come "from nothing".

Web1 Answer. According to Stephen Hawking in 'A Breif History of Time', the total energy of the universe is zero. That's because there's negative energy associated with gravitational attraction. Add positive to an equal amount of negative, and you get zero. So saying energy can't be created or destroyed just means you can't change the total energy ... WebWhen energy is transferred within a system, energy can be dissipated. This is where energy is ‘wasted’ by being transferred out to the surroundings. Energy becomes stored in less useful ways.
