WebThe potential energy can be negative when the body is kept at the reference-point possessing zero energy. If the object is kept below the earth’s surface, it possesses … WebIn 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.
