Across
  1. 6. is the vector from the initial location to the final location
  2. 8. is a tangential force acting on an object that opposes the sliding of that object on an adjacent surface with which it is in contact
  3. 13. a tilted surface
  4. 16. the unit of force
  5. 18. mechanism compost by rope and wheel used to elevate heavy objects onto upper level
  6. 19. on an object that is being supported by a surface is the component of the supporting force that is perpendicular to the surface
Down
  1. 1. is the gravitational force acting downward on the object
  2. 2. has done nothing to do with spatial direction
  3. 3. is a vector quantity. An object undergoes a vector displacement in a time interval
  4. 4. sum of a number of vectors of force
  5. 5. the velocity of the body travelling in a straight line remains the same
  6. 7. is a measure of how much matter there is in an object
  7. 9. measure the time rate-of-change of velocity
  8. 10. is the average velocity evaluated for a time interval that approaches zero
  9. 11. motion in one spatial dimension
  10. 12. acting on a string is the applied force tending to stretch it
  11. 14. three dimensional of an object ex.m3, cm3
  12. 15. how much ground an object has covered during its motion
  13. 17. is the motion of an object where the only force acting on the object is its weight
  14. 20. most usually a change is something per unit of time
