Presentation Transcript

  1. Types of Energy Everything should be off your desk except your notes page and your pencil. Fill in your notes as we go along

  2. Potential Energy • Energy of POSITION or STORED energy

  3. 1. CHEMICAL ENERGY • energy stored in the bonds of atoms Examples are • gasoline (petroleum) • FOOD • Natural gas • Propane • Coal

  4. 2. NUCLEAR ENERGY • Energy stored in the nucleus of an atom Examples are • Nuclear reactors • uranium

  5. 3. STORED MECHANICAL/ Elastic ENERGY • Energy stored in objects because of the application of a force Examples are • Stretched rubber band • Compressed springs in a mattress or couch

  6. 4. GRAVITATIONAL ENERGY • Energy stored because of somethings place or position Examples are • Water at the top of a dam • Rock at the top of a hill • Book sitting on a desk

  7. KINETIC ENERGY • Is energy of MOTION

  8. 5. RADIANT ENERGY • Electrogmagnetic energy that travels in waves Examples are • Visible light • Solar energy • Radio waves • X-rays • Gamma rays

  9. The ELECTROMAGNETIC SPECTRUM TRAVELS IN WAVES NOT ALL LIGHT IS VISIBLE

  10. 6. THERMAL ENERGY • Energy from the vibration of atoms and molecules Examples are • HEAT • Geothermal heat

  11. 7. MOTION (Mechanical) ENERGY • Energy from the movement of objects Examples are • Wind (turns windmill) • Hydropower- going over dam • Ball flying through air • You walking

  12. 8. SOUND ENERGY • Energy of longitudinal waves Examples are • Music • Talking • Waves travel into ear, hits eardrum that vibrates hairs and tiny bones in ear, then sends signals to brain.

  13. 9. ELECTRICAL ENERGY • Energy from the movement of electrons Examples are • Electricity • Lightning

  14. Now… • Use your notes to fill in the blanks on the back of your paper. • Note that there is a word bank at the bottom. • Words can (and will) be used more than once. • Papers are due when you leave class today (need to be complete!!)
