Answer:
A simple machine is a device that reduces the force needed to move something by increasing the DIstance, length, span, or displacement over which the force must act.
Step-by-step explanation:
simple machine, any of several devices with few or no moving parts that are used to modify motion and the magnitude of a force in order to perform work. They are the simplest mechanisms known that can use leverage (or mechanical advantage) to increase force.simple machine, any of several devices with few or no moving parts that are used to modify motion and the magnitude of a force in order to perform work.
