Energy comes in many different forms, but they share a common bond - they are the source of change, the root of the force. Energy moves through our world by force and action, changing from one form to another. Of course the energy is really the same, but it is our human need to classify what we see that creates the separate designations. We artificially separate energy into different categories for our ease of use. For most of these categories...
