Across
  1. 2. an attractive force that exists between all objects that have mass.
  2. 6. a wave in which the disturbance is perpendicular to the direction the wave travels.
  3. 8. a tiny particle inside an atom's nucleus that has no electrical charge.
  4. 9. a tiny, positively charged particle found in the center of every atom.
  5. 14. the displacement of the spectrum to shorter wavelengths in the light coming from distant celestial objects moving toward the observer.
  6. 17. a material in which a wave travels.
  7. 18. a wave that can travel only through matter.
  8. 22. a measure of the distance an object travels in a given amount of time.
  9. 23. the interaction between electric charges and magnets.
  10. 24. an object at rest will stay at rest, and an object in motion will stay in motion unless a force acts on the object.
  11. 25. a representation of the information that is communicated.
  12. 28. the change in direction of a wave as it changes speed in moving from one medium to another.
  13. 29. contact force that resists the sliding motion of two surfaces that are touching.
  14. 31. the combination of all the forces acting on an object.
  15. 32. a device that uses an electric current to produce motion.
  16. 33. a process where two light atomic nuclei combine to form a heavier nucleus, releasing a tremendous amount of energy in the process.
  17. 34. the change in direction of a wave when it travels by the edge of an object or through an opening.
  18. 37. when an object applies a force on another object, the second object applies a force of the same strength on the first object but the force is in the opposite direction.
  19. 39. a tiny, negatively charged particle that zooms around the center of an atom.
  20. 40. an electric signal whose values change between two values.
  21. 41. a wave in which the disturbance is parallel to the direction the wave travels.

Down
  1. 1. a force of attraction or repulsion created by a magnet.
