Efficiency measures how much of the work put into a machine is actually converted into useful output work. No machine is 100% efficient because some energy is always lost as heat due to friction.

( AMA = \fracF_\textoutF_\textin = \frac400 , \textN20 , \textN = \mathbf20 ) Efficiency measures how much of the work put

No machine is 100% efficient because some work is always lost to friction as heat. Efficiency compares the work output to the work input. Formula: Efficiency measures how much of the work put
