Energy conservation, dissipation, and power

Energy-flow diagram of an electric motor with electrical input, useful kinetic output, and dissipated thermal energy and sound labelled

Energy is conserved in any system: input energy is transferred between stores, not created or destroyed. Some transfers are useful, while some are dissipated to less useful stores such as heating the surroundings or producing sound.
