Question

Quizplus · Accepted Answer

As the object is lowered into a deep hole in the surface of the Earth, it moves closer to the center of the Earth, where the gravitational force is stronger. This results in a decrease in the object's gravitational potential energy because the object's distance from the Earth's surface decreases, which is the source of its potential energy.
