Examples of forms of energy in classical mechanics include heat, light, kinetic (movement) or potential energy. People can use the changes to do work that is useful. This is why Perpetual motion machines do not exist and could never exist it would break a fundamental law of physics. Energy only ever changes its form it is neither created nor destroyed. Another example: In the Sun (or any star), Nuclear Fusion changes mass into heat and light ( Electromagnetic Radiation), which travels to Earth and is used by plants to create food (chemical energy) via photosynthesis, which can be eaten by animals allowing them to move (kinetic energy). For example, exercising changes energy from food into kinetic (motion) energy. This means that anything that uses energy is changing the energy from one kind of energy to another. The law forms the basis of the principle of conservation of energy. The very first law of thermodynamics states that energy can neither be created nor destroyed it can changed only from one form to another.
