  1. 7. states that when one object exerts a force on a second object, the second object exerts a force on the first object that is equal in strength and in the opposite direction
  2. 9. states that an object moving at a constant velocity keeps moving at that velocity unless an unbalanced force acts on it
  3. 10. rate of change of velocity; can be calculated by dividing the change in the velocity by the time it takes the change to occur
  4. 11. gravitational force exerted on an object
  5. 13. tendency of an object to resist any change in its motion
  6. 15. states that if no external forces act on a group of objects, their total momentum does not change
  7. 18. a push or pull exerted on an object
  8. 20. distance and direction of an object’s change in position from the starting point
Down
  1. 1. a force that is directed toward the center of a curved or a circular path
  2. 2. a change in an object’s position relative to a reference point
  3. 3. attractive force between two objects that depends on the masses of the objects and the distance between them
  4. 4. states that the acceleration of an object is in the same direction as the net force on the object, and that the acceleration equals the net force divided by its mass
  5. 5. the length an object travels, measured in SI units of meters
  6. 6. the maximum speed an object will reach when falling through a substance, such as air
  7. 8. describes the fall of an object on which only the force of gravity is acting
  8. 12. distance and object travels per unit of time
  9. 14. the speed and direction of a moving object
  10. 16. force that opposes the motion of objects that move through the air
  11. 17. force that opposes the sliding motion between two touching surfaces
  12. 19. acceleration of an object toward the center of a curved or circular path
