Down
  1. 1. the quantity of matter that determines how much an object accelerates when a force is applied
  2. 2. having less magnitude or size compared to another quantity
  3. 3. becomes smaller or less in amount or magnitude
  4. 4. the mixture of gases surrounding Earth that can create resistance to motion
  5. 7. the force that occurs in response to an action force, equal in size and opposite in direction

  7. 10. the measurement of how long something is, often used to represent magnitude in diagrams
  8. 12. the process by which an unstable atomic nucleus loses energy by emitting radiation
  9. 13. the speed of an object in a specific direction
  10. 14. the outer area of an object that can interact with air or other materials
  11. 18. a pulling force transmitted through a rope, string, or spring
  12. 19. the amount of matter in an object
