  1. 4. an attractive force that exists between all objects that have mass
  2. 6. the combination of all the forces acting on an object
  3. 10. the forces two objects apply to each other
  4. 12. the tendency of a object to resist a change in its motion
  5. 15. law that states that the acceleration of an object is equal to the net force exerted on the object divided by the object's mass
  6. 16. a push or pull on an object
  7. 19. law that states that if the net force acting on an object is zero, the motion of the object does not change
