Across
  1. 3. the size or quantity of something
  2. 6. the force that one massive object exerts to attract another object to it; expressed in the weight of an object
  3. 7. the fastest speed a falling object can reach; occurs when air resistance becomes equal to the force due to gravity
  4. 9. only these forces can be added together
  5. 10. when forces acting in opposite directions are exactly equal
  6. 16. a drawing with force vectors whose sizes and directions represent the magnitudes and directions
  7. 18. the abbreviation for gravity
  8. 19. recognized when an object's position from a reference point changes
  9. 20. the speed of something in a given direction
  10. 22. the abbreviation for normal force
  11. 23. a relationship between variables in which an increase in one variable causes an increase in the other, or vise-versa
  12. 26. the sum of all the forces that act on an object
  13. 27. the curved motion that results form the combination of an object's horizontal inertia and the gravitational force pulling the object downward
Down
  1. 1. the law that says any two objects in the universe are attracted to each other and that the force of attraction between the two objects is affected by the masses of the two objects and the distance between the two objects
  2. 2. a relationship between variables in which an increase in one variable causes a decrease in the other variable, or a decrease in one variable causes an increase in the other
  3. 4. when forces acting in opposite directions are unequal
  4. 5. what forces that act in opposite directions do to each other
  5. 8. a space that contains no matter (even air)
  6. 11. the support force a surface exerts on an object; always at a 90 degree angle to the surface
  7. 12. a state in which the only force acting on an object is the force of gravity
  8. 13. the abbreviation for friction
  9. 14. a resistance to motion caused by two surfaces rubbing against each other
  10. 15. what forces are measured in
  11. 17. a push or a pull
  12. 21. a quantity that has both a size and direction
  13. 24. the abbreviation for a push or pull
  14. 25. what forces that act in the same direction do
