  • $\begingroup$ What changes when you use a lever? You don't just get a larger force. Same goes for the other simple machines: pulley, inclined plane, screw, etc. $\endgroup$ – ahemmetter Mar 16 '18 at 7:53

the output displacement is reduced in the same proportion by which the output force is increased over the input force. This conserves energy.
