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. Four pulleys can be arranged into a  thing called a block & tackle that can divide the force  required to lift something by four. But, the rope must be extended  four times as long to do this.
