A movable pulley is a pulley exactly where when you transfer a heavy object, the drum moves with it. There is no adjust in the path of the force you need to apply, but the load will “feel” lighter than it actually is. For instance, if you might be hauling a heavy hay bale up the barn’s attic, a moveable pulley will make the load feel a whole lot lighter, even though you might be pulling in the exact same path.
