Here's how it works:
* Fixed Pulley: A fixed pulley is attached to a stationary point. When you pull down on the rope, the pulley changes the direction of the force upwards, making it easier to lift an object.
* Movable Pulley: A movable pulley is attached to the object being lifted. When you pull down on the rope, the pulley changes the direction of the force upwards, and also reduces the amount of force needed to lift the object.
