  1. Forms of Energy Remember… all forms of energy are either kinetic or potential

  2. Kinetic Energy • Energy of motion

  3. Potential • Stored energy • Positional energy • PE=heightXmassXgravity

  4. Thermal Energy • Definition: Heat. Vibration and movement of the particles in a substance • Examples: geothermal, sun, fire • **Friction produces heat nrg

  5. Motion EnergySometimes called Mechanical Energy • Definition: Movement of objects and substances from one place to another. • Examples: wind (air particles), transportation

  6. Gravitational Energy • Definition: Energy due to objects height above the earth’s surface. • Mass & height determine amount of PE • Examples: marble top of ramp, water behind hydropower

  7. Stored Mechanical Energy • Definition: Energy stored in objects by applying force (push or pull). • Examples: compressed springs and stretched rubber bands

  8. Radiant (Light) Energy • Definition: Electromagnetic energy that travels in transverse waves • Examples: light, X rays, radio waves, sun

  9. Chemical Energy • Definition: Energy stored in the bonds of molecules. The energy that holds the particles together. • Examples: biomass (wood), fossil fuels (oil), batteries, living organisms-plants/animals

  10. Electrical Energy • Definition: The movement of electrons, usually thru a wire. • Examples: • lightning • Any electric appliances

  11. Sound Energy • Definition: Movement of energy through waves; vibration of air particles. • Examples: music, speaking, noise, tree falling in forest…

  12. Nuclear Energy • Definition: Energy stored in the nucleus of an atom • Example: • fission-nuclear power plants, bombs • fusion-energy produced in sun

  13. Exit Ticket • First and last name • Draw the lab set up on page 2 or 3: marble, ramp, ½ cup • Label as many forms of energy as you can. Point to exactly where they are in your picture.

  14. QUIZ TIME! What type of energy cooks food in a microwave oven? ELECTROMAGNETIC ENERGY What type of energy is the spinning plate inside of a microwave oven? MECHANICAL ENERGY

  15. QUIZ TIME! Electrical energy is transported to your house through power lines. When you plug an electric fan to a power outlet, electrical energy is transform into what type of energy? MECHANICAL ENERGY

  16. O.A. 2/15Categorize Forms NRG into TYPES of NRG • Sort the forms of energy into the two TYPES of energy: Kinetic or Potential: • electrical, sound, gravitational, nuclear, chemical, motion, thermal, radiant, mechanical, elastic, etc.
