Här är en uppdelning:
* Energy transformations involve energy changing from one form to another. For example, a light bulb transforms electrical energy into light and heat.
* Energy is not created or destroyed means that the total amount of energy in a closed system remains constant. Det ändrar helt enkelt formen.
* Lagen om bevarande av energi is a fundamental principle in physics and applies to all energy transformations.
In other words, energy can be transferred and transformed, but it can never be created or destroyed.
