The correct statement about simple machines is:
**Simple machines do not change the amount of work done.**
Simple machines can make work easier by changing the direction of the force or increasing the distance over which the force is applied, but they do not increase the total amount of work done; the work input equals the work output (ignoring friction and other losses). The other statements are not accurate in the context of how simple machines function.
