Science chapter 3

  1. What is kinetic energy?
    Kinetic energy is the energy of motion
  2. What is potential energy?
    Potential energy is stored energy or energy that an object has due to its position.
  3. How does potential energy change into kinetic?
    Example: If you were on a rollercoaster at the top of the hill the car is at its highest when you're a the top you have the most potential energy when you go down the hill you are changing into kinetic because you are in motion.
  4. How does kinetic energy change into potential energy?
    When the car is increasing in speed you have the most kinetic energy when you back up a hill it changes back into potential.
  5. What is sound energy?
    Sound energy is energy of vibrations carried by air,water,or other matter.
  6. What is radient energy?
    Radient energy is energy that travels as waves and can move through empty space.
  7. What is electrical energy?
    Electrical energy is energy carried by electricity.
  8. What is mechanical energy?
    Mechanical energy is energy an object has due to its motion, postion, or condition.
  9. What is nuclear energy?
    Nuclear energy is energy produced when an atom splits apart or when two atoms join to form one atom.
  10. What is chemical energy?
    Chemical energy is energy stored in the way atoms are connected to each other.
  11. What is thermal energy?
    Thermal energy is energy of the movement of atoms and molecules.
  12. What are the seven forms of energy?
    Sound, radiant, electrical, mechanical, nuclear, chemical, and thermal.
  13. How does radiant energy travel?
    Radiant can travel as waves an can move through empty space. Also, radiant energy is used to diagnose disease, to cook food, to send radio and TV signals, and for other purposes.
  14. how does sound energy travel?
    Sound energy in waves that move only through matter. Also, living things use sound energy for communication and navigaton. People also use sound for entertainment and to diagnose disease.
  15. what is vibration?
    Vibration is rapid back and forth motion of air or other matter.
  16. true or false: Does short wavelength have a low frequency?
    False
  17. What is a wavelength?
    A wavelength is the distance from one point on one wave to the same point on the next wave.
  18. What are the rays that can harm your skin and give you sunburns?
    Ultraviolet rays.
  19. Energy can change from one form to another, but under ordinary conditions no energy is lost or created.

  24. A rapid back and forth motion of air or other matter is called a ____.
    Vibration.
  25. the energy of vibrations carried by air, water, or other subtances is _____.
    sound energy
  26. the energy released by chemical changes is called____.
    chemical energy
  27. The distance from one point on a wave to the same point on the next wave s called a  ____.
    Wavelength
  28. The energy carried by electricity is called ___.
    electrical energy
  29. The energy that travels in waves and can move through empty space is ___.
    Radiant energy
  30. The number of waves passing a point in a given amount of time is the ____.
    frequency
  31. As an object gets warmer, its ___ increases as the atoms and moleculs it is made of move faster.
    Thermal energy
  32. The energy an object has because of its position, motion, or condition is called ____.
    mechanical energy.
  33. Kinetic or potential energy: a moving soccer ball
    Kinetic energy
  34. Kinetic or potential energy: a bicycle stopped at the top of a hill
    potential energy
