Energy models

  1. 1. Energy Models Transferring & TransformingEnergy
  2. 2. Potential Energy and Kinetic Energy Quick Review  Potential Energy = Stored Energy  Kinetic Energy = Happening Energy (energy of motion)  Energy can change from one form to another, HOWEVER … IT IS NEVER LOST
  3. 3. Potential Energy to Kinetic Energy Energy is constantly changing from potential energy to kinetic energy and back again. Can we explain this using a model? OF COURSE!
  4. 4. Baseball Model The baseball has potential energy when it is in the glove. The potential energy is transferred to kinetic energy when the ball is released. The kinetic energy is then transferred back to potential energy when the catcher catches the ball. This change happens each time the ball is thrown.
  5. 5. Now Your Turn Pendulum Model Explain the transfer of energy in the pendulum. Indicate where the PE (potential energy) is the greatest/least and where the KE (kinetic energy) is greatest/least.
  6. 6. Energy Transformations Quick review Mrs. G. Chen – Ring a bell? Can you list the types of energy? Mechanical Radiant (Electromagnetic) Sound Gravitational Chemical Heat (Thermal) Electric Nuclear
  7. 7. Let’s Make a Model Construct a model using the following materials to illustrate the transformation of energy. Label each energy transformation
  8. 8. Questions?
