  1. Welcome Back Minions!!! Time to learn some science!!!

  2. Review… • Energy • The ability to do work or cause change. • Work • The transfer of energy. • Power • The rate at which work is done • Kinetic Energy • Energy of motion. • Formula for Kinetic Energy

  3. Review • Define Potential Energy • Stored energy that results from the position or shape of an object. • What are 2 types of Potential Energy • Gravitational and Elastic Potential Energy • Formula For Gravitational Potential Energy • What factors affect Kinetic Energy? • Mass and Velocity • What factors affect Potential Energy? • Height and Weight

  4. Mechanical Energy • Add an object’s Potential Energy to its Kinetic Energy and you have MECHANICAL ENERGY!!!

  5. Energy Type #2 • Examples: • Melting Ice Cream • Evaporating Water • Molten Rock • Thermal Energy • The total Potential and Kinetic energy of atomic particles.

  6. Energy Type #3 • Examples: • Scoot across a carpet and shocking someone • Lightning • Power in your home to run appliances • Electrical Energy • The energy of electrical charges

  7. Energy Type #4 • Examples: • Found in foods you eat • Found in objects around you • Found in all molecules! • Chemical Energy • Energy stored or released from chemical bonds in molecules

  8. Energy Type #5 • Examples: • Fission (breaking apart a nucleus of an atom) • Fusion (Making a nucleus bigger by collision) • Without this, no sun or sunshine!!! • Nuclear Energy • Energy stored or released in the nucleus of an atom

  9. Energy Type #6 • Examples: • Light so we can see • Microwaves to heat our food • X-Rays to see if any bones were broken • Electromagnetic Energy • Waves that have both electrical and magnetic properties

  10. Warm-Up • Give an example of the following: • Mechanical Energy • Thermal Energy • Chemical Energy • Electrical Energy • Nuclear Energy • Electromagnetic Energy

  11. Introduction… • How do power plants make electricity? • How does your body make energy? • How does your cell phone battery give your cell phone power?

  12. Energy Transformations • Most forms of energy can be transformed into other forms! • Energy Transformation- A change from one form of energy to another.

  13. Single Transformations • What does this term mean? • One transformation • Toaster = Electrical to Thermal • Cell Phone = Electrical to Electromagnetic • YOU! = Chemical to Mechanical

  14. Multiple Transformations • What does this term mean? • Multiple Transformations • Match = • Mechanical to … • Thermal to… • Chemical to… • Thermal to… • Light!

  15. Multiple Transformations • You try one!

  16. Transformations between…KINETIC & POTENTIALENERGY!

  17. Transformations between…KINETIC & POTENTIALENERGY!

  18. Transformations between…KINETIC & POTENTIALENERGY!

  19. Conservation of Energy • Law of Conservation of Energy • Energy cannot be created nor destroyed. • One form of energy transforms into another, no energy is “destroyed” in the process.

  20. Energy & Friction

  21. Energy & Matter • Einstein discovered that matter can be transformed into energy! • Destroying a small amount of matter releases a great amount of energy! • Matter and energy together must be conserved! • (Cannot be turned to nothingness!)

  22. Closing… • How does a car transform energy? • How does Juggling transform back and forth between potential to kinetic? • Why doesn’t a top keep spinning? • What happens to the energy?
