  • True or false; “Energy is never lost during an energy transformation, it just transfers out of the system into the surrounding system”
    True
  • *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?
    25 J
  • Look at the task card, complete the Statement that will describe the transformation being shown. Chemical energy →
    Light, Thermal, & Sound energy.
  • When does an object have Potential Energy?
    At rest, when not moving / storing energy
  • Look at the roller coaster diagram above, What location in the coaster ride does KE transform into GPE the energy?
    Location A
  • Gravitational Potential Energy is the energy an object has due to its ___________
    height & mass
  • Thermal Energy ALWAYS moves from ...
    Hot to Cold
  • 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?
    Sound 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
  • Energy efficiency means using ______ energy to provide the same amount of useful energy.
    less
  • *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

  • When does an object have Potential Energy?
    At rest, when not moving / storing energy
  • Describe the particle movement when a substance is heated or cooled.
    heated
  • What type of Energy is being represented in the photo?
    Elastic Energy
  • Look at the task card, complete the Statement that will describe the transformation being shown. Light energy →
    Chemical (current )
  • What is the energy transformation sentence that describes the energy type before & after the transformation?
    Chemical energy → Light, Thermal, & Sound energy.
  • As Potential Energy increases, kinetic energy- (increase, decrease, stay the same?)
    decreases
