  4. 6. Ratio of the force to the normal force between the sliding surfaces.
  5. 10. y=(y2-y1)/(x2-x1)
  6. 12. The force that opposes and reduces motion on a large and microscopic scale.
  7. 14. x=xo+VoT+0.5AT^2
  8. 15. A path of an object with mass in motion that travels through space as a function of time
  9. 16. The force that results from gravity on an object.
  10. 17. The tendency of an object to stay at rest or remain in motion.
