Across
  1. 2. The speed and direction an object is moving
  2. 4. The energy an object has because of its position; stored energy
  3. 5. The change in the position of an object
  4. 8. A change in an objects speed or direction
  5. 9. the force that pulls objects toward each other
  6. 10. If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object
  7. 12. Force Forces that are unequal in size or direction and that changes an object’s motion; Net Force DOES NOT equal 0!
  8. 17. A push or pull
  9. 18. the tendency of an object to resist a change of motion
  10. 19. Force the total of all forces acting on an object
  11. 20. The ability to do work or cause change
  12. 21. Force Forces that act against each other and do not cause a change in motion; Net force is 0!
Down
  1. 1. An object’s acceleration depends on its mass and on the net force acting on it (F=ma)
  2. 3. The steepness of a graph line; the ration of the vertical change (the rise) to the horizontal change (the run)
  3. 6. speed The speed of an object at one instant of time
  4. 7. An object at rest will remain at rest unless acted upon by a nonzero net force. An object moving at a constant velocity will continue moving at a constant velocity unless acted upon by a nonzero net force
  5. 11. the overall rate of speed at which an object travels
  6. 13. Energy that an object has due to its motion
  7. 14. the resistance that one surface or object encounters when moving over another
  8. 15. the distance an object moves per unit of time such as miles per hour
  9. 16. the unit of force in a metric system
