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 by allowing the force to be applied over a longer distance, but they do not increase or decrease the total amount of work done. The work done (force applied times distance moved) remains the same.
