Across
  1. 5. speed and direction of a moving body
  2. 7. a push or a pull; has a size and direction
  3. 9. a force that resists motion
  4. 10. measures an object's tendency to remain at rest or keep moving with constant velocity
  5. 12. change in velocity divided by the amount of time needed for that change to take place; occurs when an object speeds up, slows down, or changes direction
  6. 13. the appearance of a straight line on a distance/time graph that indicates a constant speed
  7. 15. distance traveled divided by the time needed to travel that distance
Down
  1. 1. force that tends to draw all bodies in the earth's sphere toward the center of the earth
  2. 2. describes unequal forces acting on an object; results in a change in the object's motion
  3. 3. law of motion that states that an object aced on by a net force will accelerate in the direction of that force
  4. 4. the appearance of a straight line on a distance/time graph that indicates a body at rest
  5. 6. law of motion that states forces act in equal (in size) and opposite (in direction) pairs
  6. 7. law of motion that states that an object will remain at rest or move in a straight line at a constant speed unless it is acted upon by a force
  7. 8. describes forces that are equal but opposite in direction; when they act on an obect, they cancel each other out and no change occurs in the object's motion
  8. 11. ca change when the force of gravity changes
  9. 14. when unequal forces change an object's motion, the object moves in the direction of the __________ force
