What is Energy?
• Energy is the ability to do work.
• There are two main types of energy:
• Potential
• Kinetic

Transcript of "Different Energy Forms"

  1. 1. ENERGY What is it and what kinds are there?
  2. 2. What is Energy? • Energy is the ability to do work. • There are two main types of energy: • Potential • Kinetic
  3. 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. 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. 5. Potential vs. Kinetic • When one increases, the other decreases.
  6. 6. Potential vs. Kinetic • When one increases, the other decreases.
  7. 7. Other Types of Energy… • Mechanical • Electromagnetic • Electrical • Chemical • Thermal • Sound
  8. 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. 9. Other examples of Mechanical Energy
  10. 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. 11. Examples of Electrical Energy
  12. 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. 13. Examples of Chemical Energy
  14. 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. 15. Examples of Thermal Energy
  16. 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. 17. Examples of Sound Energy
  18. 18. What is Electromagnetic Energy? Includes energy from gamma rays, x-rays, ultraviolet rays, visible light, infrared rays, microwave and radio bands
