Presentation Transcript

  1. Energy Review Physical Science

  2. The Equations! • Kinetic Energy = • Gravitational Potential Energy = m g h

  3. Conservation of Energy! • Important Equation • Energy can be neither created nor destroyed but only conserved.

  4. Common Forms of Energy • Potential and Kinetic (aka mechanical) • Thermal • Chemical • Electrical (kind of) • Electromagnetic • Nuclear

  5. Methods of Energy Production • Nonrenewable (fossil fuels, natural gas, etc.) • Hydroelectric Plants • Geothermal Plants

  6. Methods Cont. • Solar Cells and Panels • Wind Turbines!

  7. Ideal System (aka a perfect world) • Energy is not lost to friction or leaking. • In short energy is conserved and perpetual motion works

  8. Real World • Energy is lost to friction • Energy is lost to the production of other forms in conversion processes (such as sound and heat) • Energy is still conserved just we can convert 100% of it into the intended form

  9. Nuclear Melt Down Japan • http://www.youtube.com/watch?v=A5UvAH11CjM • Hint: Question 10
