Question

When using a pulley system, force (increases/decreases) and distance (increases/decreases).

Answer 1

In a pulley system, when you use a pulley to lift a load, the force required to lift that load decreases, while the distance you must pull the rope increases. This is based on the principle of mechanical advantage provided by the pulley system. Essentially, you trade off force for distance: by pulling the rope a longer distance, you can lift the load with less force.
