Across
  1. 2. as distance doubles, the gravity reduces by 4 times
  2. 4. a force that keeps something moving in a circle
  3. 7. The force of gravity acting on an objects mass
  4. 9. the space between two objects, used in gravity calculations
  5. 12. gravity depends on mass and distance-more mass means more pull, more distance means less

  7. 14. the amount of matter in an object
  8. 15. a number that shows how strong gravity is between two masses
Down
  1. 1. a force that pulls objects toward eachother
  2. 3. a force that pulls objects together
  3. 5. the area around a mass where gravity can be felt
  4. 6. the speed needed to break free from a planets gravity
  5. 8. the strength of gravity between two objects
  6. 10. the point where an objects mass is balanced
  7. 11. a curved path an object takes around another due to gravity
