Across
  1. 3. The maximum speed an object will reach when falling through a substance, such as air.
  2. 8. Distance an object travels per unit of time
  3. 10. Force that opposes the motion of objects that move through the air.
  4. 12. Force that opposes the sliding motion between two touching surfaces.
  5. 13. Rate of change of velocity; can be calculated by dividing the change in the velocity by the time it takes the change to occur
  6. 15. Distance and direction of an object's change in position from the starting point.
  7. 17. A force that is directed toward the center of a curved or circular path.
  8. 18. 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.
  9. 19. A change in an object's position relative to a reference point.
  10. 20. States that if no external forces act on a group of objects, their total momentum does not change.
Down
  1. 1. 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. 2. States that an object moving at a constant velocity keeps moving at that velocity unless an unbalanced force acts on it.
  3. 4. Attractive force between two objects that depends on the masses of the objects and the distance between them.
  4. 5. Gravitational force exerted on an object
  5. 6. Describes the fall of an object on which only the force of gravity is acting.
  6. 7. Acceleration of an object toward the center of a curved or circular path.
  7. 9. The length an object travels, measured in SI units of meters.
  8. 11. A push or pull exerted on an object.
  9. 14. Tendency of an object to resist any change in its motion.
  10. 16. The speed and direction of a moving object
