Input Force (Effort) The force exerted on a machine. The input force moves the machine a certain distance. https://www.youtube.com/watch?v=y maNWwfPIS4

Output Force The force a machine exerts on an object. The output force should be greater than the input force.

Efficiency This is the comparison of the output work to the input work. A Machine is efficient if the output is greater than the input. However, no machine gives 100% efficiency.

Compound Machine A device that combines two or more simple machines.
