• Forms of potential energy

  • Chemical
  • Gravitational
  • Elastic
• Chemical potential energy


  Stored in chemicals such as in food, fuel, or batteries
• Gravitational potential energy


  Stored in things above the surface
• Elastic potential energy


  Stored in things that stretch or compress, such as a rubber band, spring, or foam mat
• Potential energy is the ability to do work
