  1. Energy Energy of Movement Electromagnetic Chemical

  2. Mechanical Energy • We have always relied on mechanical energy to do work. • History is dotted with many discoveries that have reduced effort required to do this work. • Wheels, pulleys, gears and levers have all been used to reduce effort

  3. Watt

  4. Chemical Energy • The chemical reactions that occur in nature all involve a change in energy level – giving off energy or requiring energy to occur • Photosynthesis and respiration in living things; chemical reactions in nature such as oxidation and electrolytic replacement • These chemical processes can be harnessed to generate other forms of energy such as electricity, heat and even light

  5. Electromagnetic Energy • Magnetic fields • Radiation

  6. Faraday

  7. Voltaire Franklin

  8. The Future • Fuel Cells • Electric Cars • Alternate Renewable Energy Sources
