  1. 2. a quantity defined as the product of the mass and velocity of an object
  2. 4. a measure of the inertia of an object and depends on amount of matter in an object
  3. 5. for every action there is an equal and opposite reaction
  4. 7. friction that occurs as an object moves through a fluid
  5. 9. a force that opposes motion between two surfaces that are in contact
  6. 12. force of gravity acts between all objects in the universe
  7. 13. the combination of all forces acting on an object
  8. 14. a measure of the force of gravity on an object
  9. 15. friction that acts on objects that are not moving
  10. 16. a force of attraction between objects that is due to their masses
  11. 17. friction that occurs when one solid surface slides over another
  12. 19. resistance to change in motion determined by mass and motion
  13. 20. a force where the net result (numbers) equal 0
Down
  1. 1. a force being applied where the net result is > 0
  2. 3. an object will remain in it's current motion until an object acts on it inertia
  3. 6. the constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity
  4. 8. friction that occurs when an object rolls over a surface
  5. 10. the rate of change of momentum of a body is directly proportional to the (net) force acting on it and takes place in the direction of that force
  6. 11. fluid friction acting on an object moving through the air
  7. 18. a push/pull which acts on (upon) an obj. to affect motion, sp/acceleration, or position
