Across
  1. 4. when objects hit and stay together
  2. 6. an object moving only due to gravity
  3. 8. a type of friction that goes against gravity
  4. 12. just magnitude
  5. 14. equal and opposite reactions
  6. 17. an object that does not move
  7. 18. objects tendency to resist a change in motion
  8. 20. a system of stars, dust and other objects that are held together by gravity
  9. 21. how far you traveled
  10. 22. the force on an object due to gravity, it changes on each planet
  11. 28. momentum stays the same before and after collisions
  12. 30. opposites
  13. 31. change in position over time
  14. 33. law of inertia
  15. 34. force = mass x acceleration
  16. 36. orbiting around another object
  17. 37. up and down line
Down
  1. 1. the force that attracts a body towards earth
  2. 2. a push or pull
  3. 3. change in velocity over time
  4. 5. the sun is one of these
  5. 7. larger objects have more gravitation force and objects that are further apart have less gravitational force
  6. 9. the brightness of a space object
  7. 10. flat line
  8. 11. forces that oppose or stop motion
  9. 13. forces that cause a change in motion
  10. 15. how far you are from your starting point
  11. 16. the distance traveled in a given amount of time
  12. 19. when objects hit and bounce off
  13. 23. speed and direction of a moving object
  14. 24. what causes seasons
  15. 25. speed that does not change
  16. 26. to spin on your axis, causes days
  17. 27. clouds of gas and dust in space
  18. 29. mass in motion
  19. 32. forces that do NOT cause a change in motion
  20. 35. must have magnitude and direction
