Potential and Kinetic Energy

  1. 1. Bellwork:List 6 different examples ofenergy.example: food; fire…
  2. 2. Potentialand Kinetic Energy
  3. 3. How is all energy divided? All Energy Potential Kinetic Energy EnergyGravitation Elastic Chemical Potential Potential Potential Energy Energy Energy
  4. 4. What is *Potential Energy?o *Energy that is stored and waiting to be used later
  5. 5. What is *Gravitational Potential Energy? o *Potential energy due to an object’s positionDon’t look down, o P.E. = mass x Rover! height x gravity Good boy!
  6. 6. What is *Elastic Potential Energy? o *Potential energy due compression or expansion of an elastic object.Notice the ball compressing and expanding
  7. 7. What is *Chemical Potential Energy?o *Potential energy stored within the chemical bonds of an object
  8. 8. What is *Kinetic Energy?o *Energy an object has due to its motiono K.E. = .5(mass x speed2)
  9. 9. *Kinetic Energy*Kinetic Energy increases withspeed.
  10. 10. Kinetic Energy*Kinetic Energy increases withmass.
  11. 11. Law of Conservation of Energy*The Law of Conservation ofEnergy states: *Energy is never created or destroyed *Energy is simply converted from one form to another (also called the First Law of Thermodynamics)
  12. 12. Law of Conservation of Energy
  13. 13. Your turn…List on your notes:Six examples of potential energySix examples of kinetic energyThank you for your attention today!!!
