Can energy be created or destroyed why
WebThe law of Conservation of Energy states that energy cannot be created or destroyed - it can only be transferred from one type to another. Part of. Physics. Dynamics. 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.

In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law, first proposed and tested by Émilie du Châtelet, means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes. If one adds up all forms of energy that were r… WebEnergy can never be created or destroyed
WebJun 2, 2024 · Matter can change form through physical and chemical changes, but through any of these changes matter is conserved.
