    EMR
    chemical
    sound
    electrical
  • A rubber band is stretched and then released. What kind of energy transformation occurs?
    stored/elastic/potential energy --> motion energy
  • What energy transformation occurs in a blow dryer? (name at least one)
    electricity into heat, motion, and sound
  • Which of the following is a type of kinetic energy?
    chemical
    gravitational
    sound
    elastic
  • What types of energy does a candle give off?
    Light and heat
  • How can you increase the potential energy stored in a spring?
    compress it, or stretch it
  • What is the energy level of a cold object?
    low thermal energy
  • What kinds of energy do you get from the sun? What type of energy does a solar panel use?
    The sun gives us light and heat. Solar panels only use light.
  • Name 5 different types of energy
    types of energy: heat, EMR/light, sound, movement, electricity, chemical, gravitation, nuclear, elastic
  • What is an example of stored energy transforming into light energy?
    Possible answers: battery to a light bulb, a candle, a glowstick
  • How much energy do loud sounds have?
    loud sound = high energy
  • What type of circuit lets energy flow from a battery to a light bulb?
    a closed circuit
  • How can you give more motion energy to a soccer ball?
    possible answer: Kick it to make it move faster
  • What is the name of the device that spins when pushed by wind, water, or steam?
    turbine
  • If you put an ice cube in a cup of hot tea, what direction does the heat energy transfer?
    The heat transfers from the hot tea to the cold ice cube.
  • When energy is transferred in a collision, what three things can you observe?
    heat, sound, change in motion energy/direction
  • Which is these is NOT a form of stored chemical energy
    coal
    a battery
    food
    a parked car
  • Sound is made when:
    particles interact with light
    objects vibrate
    waves travel through space
    heat transfers to a warmer object
  • When a moving object slows down, what happens to its energy?
    It has less motion energy. Some of it is transferred to other objects, such as the ground or the air
  • What does conservation of energy mean?
    Energy can be neither created nor destroyed, it can only transfer to other objects or change form
  • Which of these is NOT a fossil fuel?
    oil
    coal
    solar
    natural gas
  • How can you measure heat energy?
    a thermometer
