Across
  1. 2. a force that acts between any two masses.
  2. 3. the friction force that acts on objects that are not moving.
  3. 7. the friction force that acts on rolling objects.
  4. 9. the overall force acting on an object after all the forces are combined.
  5. 10. the distance an object travels divided by the time it took to get there
  6. 13. a force that opposes the direction of motion of an object as it slides over a surface.
  7. 14. a measure of the inertia of an object.
  8. 16. the length between a start point and end point with a direction
  9. 18. a force that opposes the motion of objects that touch as they move past each other.
  10. 19. the tendency of an object to resist a change in its motion.
Down
  1. 1. fluid friction acting on an object moving through the air
  2. 4. are forces that combine to produce a net force of zero.
  3. 5. the force of gravity acting on an object.
  4. 6. the motion of a falling object (projectile) after it is given an initial forward velocity.
  5. 8. a push or a pull that acts on an object.
  6. 11. the length between two points
  7. 12. a force that results when the net force acting on an object is not equal to zero.
  8. 15. (N) is the unit of measure for force
  9. 17. is the constant velocity of a falling object when the force of air resistance equals the force of gravity.
  10. 18. opposes the motion of an object through a fluid.
