Presentation Transcript

  1. Energy and Energy Transformations Mrs. Knicely

  2. Potential Energy • Potential Energy- energy that a piece of matter has because of its position or because of the arrangement of parts

  3. Kinetic Energy • Kinetic Energy- energy that is involved with motion • ANYTHING that involves with motion has kinetic energy

  4. Electrical Energy • Electrical Energy- moving electric charges • Electrical energy is very important in our everyday life. There are electric charges everywhere you go!!

  5. Chemical Energy • Chemical Energy- energy that has anything to do with chemicals • When you put certain chemicals together and they make an explosion, that is chemical energy

  6. Sound Energy • Sound Energy- anything that has to do with sound has sound energy • For example, when you hit a tuning hammer on something it will make a sound. That has sound energy.

  7. Elastic Energy • Elastic Energy- anything that stretches or has a spring • Thing like rubber bands, trampolines, and even your muscles have elastic energy!!

  8. Solar Energy • Solar Energy- energy that comes from the sun

  9. Magnetic Energy • Magnetic Energy- energy generated due to magnetic field

  10. Potential Energy transforming to Kinetic Energy • When energy changes from kinetic to potential, that means the object was at rest but now it moving.

  11. Videos!!!!!! Title: What is Kinetic and Potential Energy? • http://www.youtube.com/watch?v=Ehx1P4adv6I Title: Potential and Kinetic Energy (Hoodwinked Version) • http://www.youtube.com/watch?v=qZ4FFWvZtyo

  12. Warm Up • Which skier has more potential energy, the skier at the top of the hill about to go down or the skier going down the hill? Explain to me why in 2-3 complete sentences.

  13. Vocabulary Terms • Transform – To convert from one form into another. • Indicate – To show. • Indicators – Observations that can tell you about the presence of some state or condition. • Inference – A plausible conclusion or interpretation based on observations or evidence. • Infer – To interpret from observations.
