Read the text about a person in motion.
Sean stood in the center of the highest diving board at a public pool. He stared
at the water far below him and then decided he did not want to jump. So, he
climbed carefully down the ladder. He walked across the flat deck to the side of
the pool. Then, he sat down and dipped his feet in the water.
When was the least gravitational potential energy stored between Sean and Earth? Assume
that Sean’s mass did not change.

The least gravitational potential energy was stored when he was sitting on the side of the pool. At this point, Sean was closest to the water level, meaning he had the least height above the ground. Since gravitational potential energy is calculated using the formula PE = mgh, where ‘h’ is the height, being at the water’s surface means he had the least potential energy compared to being on the diving board or climbing down.
When Sean stood on the diving board, he was at the highest point, maximizing his potential energy. As he climbed down, his potential energy decreased, but not as much as when he finally sat at the water’s edge, where the height—h—was zero. Thus, the thrilling dive transformed into a calming sit, all while minimizing potential energy!
