Across
  1. 7. a force of attraction between masses
  2. 12. the change of velocity per unit of time
  3. 13. the maximum speed an object can obtain during free fall through air
  4. 14. a force acting between surfaces in contact. This force acts to resist motion.

  6. 20. the location of an object
  7. 22. a unit of mass
  8. 23. a section of a vehicle designed to absorb energy during a collision and protect passengers
  9. 26. any factor that can be changed
  10. 27. in math or physics, the steepness of a line on a graph
  11. 28. the force exerted by air molecules on objects moving through air
  12. 29. the distance traveled by an object in a unit of time
  13. 30. a symbol that indicates change in a quantity
Down
  1. 1. a restriction or limitation
  2. 2. energy of motion
  3. 3. the sum of all the forces acting on a mass
  4. 4. toward it
  5. 5. total distance divided by total time.
  6. 6. a standard for evaluating or testing something
  7. 8. an interaction between objects. A push or pull.
  8. 9. when one object hits another object
  9. 10. to pull toward each other
  10. 11. a measurement of the force of gravity from a massive object (such as Earth) pulling another
  11. 15. force applied over a period of time
  12. 17. energy stored in the position or condition of an object
  13. 18. usable power that can be transferred or converted to different forms, but cannot be created or
  14. 19. how far between two objects or locations
  15. 21. a unit that describes measurement of force
  16. 24. a measure of the quantity of matter in an object
  17. 25. a unit of energy
