Transcript

  • 1. ENERGY What is it and what kinds are there?
  • 2. What is Energy? • Energy is the ability to do work. • There are two main types of energy: • Potential • Kinetic
  • 3. Potential Energy • Energy that is stored and being held, waiting to be used is potential energy. • Examples: • A car parked in a parking lot • A child at the top of a slide • A ball sitting on a table • Someone pulling a arrow back on a bow
  • 4. Kinetic Energy • The energy of motion is kinetic energy. • Examples: • Rolling a ball down a hill • Going down a hill on a roller coaster • Riding your bicycle
  • 5. Potential vs. Kinetic • When one increases, the other decreases.
  • 6. Potential vs. Kinetic • When one increases, the other decreases.
  • 7. Other Types of Energy… • Mechanical • Electromagnetic • Electrical • Chemical • Thermal • Sound
  • 8. What is Mechanical Energy? o Energy due to a object’s motion (kinetic) or position (potential). The gears in a watch have mechanical energy. When the gears turn it moves the arms of the watch.
  • 9. Other examples of Mechanical Energy
  • 10. What is Electrical Energy? o Energy caused by the movement of electrons o Easily transported through power lines and converted into other forms of energy
  • 11. Examples of Electrical Energy
  • 12. What is Chemical Energy? o Energy that is available for release from chemical reactions. The chemical bonds in a matchstick store energy that is transformed into thermal energy when the match is struck.
  • 13. Examples of Chemical Energy
  • 14. What is Thermal Energy? o Heat energy o The heat energy of an object determines how active its atoms are. A hot object is one whose atoms and molecules are excited and show rapid movement. A cooler object's molecules and atoms will show less movement.
  • 15. Examples of Thermal Energy
  • 16. What is Sound Energy? Sound is the movement of energy through substances in waves.  Sound is produced when a force causes an object or substance to vibrate.
  • 17. Examples of Sound Energy
  • 18. What is Electromagnetic Energy? Includes energy from gamma rays, x-rays, ultraviolet rays, visible light, infrared rays, microwave and radio bands
