Quizplus · Accepted Answer

As the object is lowered into a deep hole, its height from the surface of the earth decreases. Potential energy depends on the height of an object, and as the height decreases, the potential energy also decreases. Therefore, the potential energy of the object must decrease as it is lowered into the deep hole.
