  1. 3. the point in an object that moves as if all of the object’s mass was concentrated at that point
  2. 10. states that forces always act in equal but opposite pairs: Newton's ________
  3. 12. the force resisting the motion when a body (such as a ball, tire, or whee) rolls on a surface
  4. 13. the combination of all forces acting on an object
  5. 14. two or more forces acting on an object that do not cancel and cause the object to accelerate
  6. 15. the resistance created by two objects sliding against each other
  7. 16. the amount of matter in an object

  1. 1. states that if the net force acting on an object is zero, the object will remain: Newton's _________
  2. 2. the friction that exists between a non-moving object and the surface that it is resting upon
  3. 4. A push or pull upon an object resulting from the object's interaction with another object
  4. 5. states that an object acted upon by a net force will accelerate in the direction of the force, and that the acceleration equals the net force divided by the object’s mass: Newton's __________
  5. 6. the point at which the velocity of an object (the speed of change of the falling object) is no longer getting faster
  6. 7. force that acts to oppose sliding between two surfaces that are touching
  7. 8. two or more forces whose effects cancel each other out and do not change the motion of an object
  8. 9. rest or will move in a straight line with constant speed
  9. 11. the gravitational force between an object and Earth
