  1. Principles of EnergyChapter 1

  2. What is Energy? • Energy is defined as the ability to produce change or do work. • Sound • Motion • Growth • Heat • Light • Technology

  3. Forms of Energy • Potential Energy: the energy that a piece of matter has because of its position or nature or because of the arrangement of parts. • Kinetic Energy: the energy of an object associated with its motion.

  4. Potential Energy • Potential Energy is stored energy and the energy of position, or gravitational energy. There are several forms of potential energy, including: • Chemical energy • Stored Mechanical Energy • Gravitational Energy

  5. Potential Energy • Chemical Energy

  6. Potential Energy • Stored Mechanical Energy

  7. Potential Energy • Gravitational Energy

  8. Kinetic Energy • Kinetic Energy is motion – the motion of waves, electrons, atoms, molecules, substances, and objects. • Types of Kinetic Energy include: • Electrical Energy • Radiant Energy • Thermal Energy • Motion Energy • Sound Energy

  9. Kinetic Energy • Electrical Energy

  10. Kinetic Energy • Radiant Energy

  11. Kinetic Energy • Thermal Energy

  12. Kinetic Energy • Motion Energy

  13. Kinetic Energy • Sound Energy

  14. Conservation of Energy • A principle in physics: the total energy of an isolated system remains constant irrespective of whatever internal changes may take place with energy disappearing in one form and reappearing in another.

  15. Conservation of Energy

  16. Conservation of Energy • Gummy Bear Experiment – Conversion of Bond Energy to Heat Energy & Light Energy
