  Chapter 9 Energy 9.9 Efficiency In any machine, some energy is transformed into atomic or molecular kinetic energy—making the machine warmer. The efficiency of a machine is the ratio of useful energy output to total energy input, or the percentage of the work input that is converted to work output. No real machine can be 100% efficient.
