A student is asked to develop a model to show how the potential energy of a system changes when the distance between two objects is altered. Which of the following best describes the process?

• Show that potential energy decreases as objects move farther apart

• Show that potential energy decreases as objects move closer together

• Show that potential energy stays the same regardless of distance

• Show that potential energy fluctuates randomly

A student is asked to reason about the energy changes in a system where a stretched spring is released. What happens to the potential energy and what evidence supports this?

• Potential energy increases; the spring stretches further

• Potential energy decreases; the spring returns to its original shape and moves

• Potential energy stays the same; the spring does not move

• Potential energy disappears; the spring vanishes
