When a pulley is applied, it typically changes the way force is applied and can allow lifting a weight with less force, while the distance over which the force is applied may increase, depending on the system.
In a simple pulley system, the user can often lift the load with less force than without the pulley, though the distance they must pull the rope to lift the load may increase.
Therefore, the correct response is:
**The force decreases, while the distance increases.**
