  • What type of Energy is being represented in the photo?
    Chemical Energy
  • What does the Law of Conservation of Energy say?
    Energy cannot be created or destroyed, just transferred or transformed
  • *Total Energy is 100 J* Scenario 1- Before we turn on the flashlight, the flashlight has a total of 100 J of chemical potential energy. How much Kinetic energy is present at this time?
    0J
  • What is the energy transformation is taking place in the photo. THINK BEFORE AND AFTER "Use your Chart" 
    Chemical energy → Light, Thermal, & Sound energy.
  • Look at the roller coaster diagram above, What location does GPE transform into KE ?
    Location B
  • What type of Energy is being represented in the photo?
    Sound Energy
  • True or false; Energy can only be transformed according to the law of conservation”
    False
  • True or false; “Energy is never lost during an energy transformation, it just transfers out of the system into the surrounding system”
    True
  • What are the two main categories of Energy?
    Potential & Kinetic Energy
  • What type of Energy is being represented in the photo?
    Nuclear Energy
  • *total Energy is 100 J *Scenario 2- the moment you click on the flashlight switch, the flashlight’s PE from the battery begins to transform into KE. The battery's potential energy is at a total of 75 J. How much KE is present at this time?
    225 J
  • Look at the roller coaster diagram, What location in the coaster ride does KE transform into GPE?
    Location A
  • What type of Energy is being represented in the photo?
    Thermal Energy
  • What type of Energy is being represented in the photo?
    Electric Current Energy
  • Scenario 3- The flashlight is on for 3 minutes, at the end of the transformation the flashlight's PE has transformed into both Light & Thermal energy. The flashlight’s Light Energy is at a total of 80 J. How much Thermal Energy?
    20 J
  • What type of Energy is being represented in the photo?
    Elastic Energy
  • True or false; Energy can only be transferred according to the law of conservation”
    Flase
  • True or false; “A consequence of the law of the conservation of energy is that the total energy in the entire universe is constant.”
    True
