Question

Can energy be created, destroyed or transformed?

Answer 1

Energy cannot be created or destroyed; it can only be transformed from one form to another. This principle is known as the law of conservation of energy. It states that the total energy in a closed system remains constant over time, although it can change forms—such as from kinetic energy to potential energy or from chemical energy to thermal energy. This fundamental concept is a cornerstone of physics and applies to all physical processes.
