  1. 4. Energy produced when electrons move from one place to another
  2. 7. Came up with the three laws of motion
  3. 8. The ability to do work
  4. 9. A force that opposes motion between two surfaces that are in contact
  5. 10. the movement of energy through substances; It moves in waves and is produced when a force makes an object to vibrate
  6. 12. Unequal forces: causes a change in the object's motion
  7. 15. A type of kinetic energy; energy stored in moving objects
  8. 16. A push or pull
  9. 18. A change in speed or direction
  10. 19. The energy of a moving object
  11. 20. Also called heat energy; is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other
Down
  1. 1. The energy stored in an object
  2. 2. A change in distance or position of an object
  3. 3. How fast an object moves over a given distance
  4. 5. A form of electromagnetic radiation; Only energy we are able to see
  5. 6. Equal forces; does not change an object's motion
  6. 11. This energy comes from the nucleus of an atom
  7. 13. The force that pulls objects toward Earth
  8. 14. An object's speed and direction
  9. 17. Energy stored in the bonds of chemical compounds
