6 Main Forms of Energy Radiant Chemical Mechanical Electrical Thermal Nuclear

The lowest form of energy is thermal which is caused by friction. The ultimate beginning form of all energy transformations is nuclear (on the sun) The form of energy that is always considered intermediate is electrical because it is usually not stored usefully and is made from the transformation of another source.

Law of Conservation of Energy Energy cannot be created Energy cannot be destroyed Energy can be transformed (change forms)
