Across
  1. 2. Motion in which all points of a moving body move uniformly in the same direction
  2. 3. A hypothetical object having mass but no physical size.
  3. 4. In specifying motion, you must specify direction; drawn to serve as frame of reference
  4. 8. change in velocity divided by time taken to make the change.
  5. 10. A longer length of time can be divided into a number of shorter periods of time, all of the same length
  6. 14. Study of motion of objects and related concepts of force and energy
  7. 15. A physical quantity that has both a magnitude and a direction
  8. 18. total displacement divided by the time interval during which the displacement occurred
  9. 19. The change in position of an object; where you are versus where you started
  10. 20. the velocity of an object at some instant or specific point in its path
  11. 21. when the magnitude of the velocity is decreasing, and velocity and acceleration point in different directions.
Down
  1. 1. the acceleration at any specific time during the motion
  2. 5. Something having position but not spatial extent, magnitude, dimension, or direction
  3. 6. Description of how objects move
  4. 7. the point or place where something begins, arises, or is derived
  5. 9. the actual time taken
  6. 11. Magnitude (numerical value) of how fast something is moving and direction in which its moving
  7. 12. Total distance traveled along its path divided by time taken to travel that distance
  8. 13. Force and why objects move
  9. 16. Measurements of position, distance or speed must have this
  10. 17. a physical quantity that has a magnitude but no direction
