1 Without its atmosphere, Earth would be a very different planet. 2  Gases in the atmosphere allow plants to photosynthesize and animals and plants to engage in respiration. 3  Water vapor, which is an atmospheric gas, is an essential part of the water cycle. 4  All weather takes place in the atmosphere.
Energy transformation can also be explained in terms of potential energy, the stored energy of a system, which can be converted into kinetic energy, the energy of movement. For example, a roller coaster sitting at the top of a hill is said to have potential energy.
Electric energy is then converted to useful mechanical energy by motors. And mechanical energy is converted to electrical energy by electric generators. The Energy Story is a good website that describes what energy is. How energy and work are related.nergy Conversion. Definition: The process of changing one form of energy into another. For example, the chemical energy in gasoline can be converted into kinetic energy (energy of motion) by an automobile engine. Definition obtained from the K - 12 Energy Education Program (KEEP).
