Work = force x distance. So a pulley that reduces  force will also increase distance -   but -   it can reduce the force needed to move something  â¦ thus making life easier.    Answer:   It depends on the number of pulleys and their arrangement. A single  pulley does not change the force required to lift something. But,  other pulley arrangements do.
