Big Ideas
  • Potential energy in a system depends on how objects are arranged when they interact at a distance.
  • Models help us understand and predict how rearranging objects in a system changes the amount of energy stored.
Essential Questions
  • How does the arrangement of objects interacting at a distance change the potential energy stored in a system?
  • What does it mean for objects to interact at a distance, and how does this relate to potential energy?
  • How can models be used to show and predict changes in potential energy within a system?
  • Why do different object arrangements store different amounts of potential energy?
  • How could changing the arrangement of objects affect the amount of usable energy in a system?
