Answer:
W
Step-by-step explanation:
"Potential energy" refers to the energy within an object in relation to its position. The most common form of potential energy is the "gravitational potential energy." This kind of potential energy is directly proportional to the height of an object.
As seen on the diagram above, the tallest height is at W. It means that, the potential energy at this point is at its greatest because of a greater gravitational pull from the Earth. On the other hand, the potential energy is least at point X because it has the shortest height and is closer to the Earth.
