Forms of energy - U.S. Energy Information Administration (EIA)
WebThe first law of thermodynamics is that matter/energy cannot be "created" or destroyed. We can convert energy from one form to another. For instance, in a car, we convert chemical energy (actually the binding energy of electrons) to heat, which in turn is converted to kinetic energy (motion). Your question has a similar answer. WebBut so far, energy seems not to be created or destroyed. Energy can be converted from one form to another, though. Mechanical energy, such as the kinetic energy of motion, can be converted to heat energy, for example in the heating of a car’s brakes when it slows down. Chemical energy in the gasoline of the car can be converted into both heat ... can a spanning tree have loops
