As a pendulum swings from its highest point to the lowest point, what happens to its potential energy?

As the pendulum swings from its highest point to its lowest point, it will lose potential energy.

As a pendulum swings from from its highest point to its lowest point, it will gain potential energy.

You rolled a rock up a hill to 50 ft high. You then rolled another rock (same mass) up the hill, but stopped at 20 ft. Which rock would have more potential energy? (Think about your pendulum lab)

The rock at 20 ft high

There would be no difference, both would have the same amount of potential energy

The rock at 50 ft high
