Across
  1. 5. force determines if an object moves and in which direction
  2. 8. third law for every action, there is an equal and opposite reaction
  3. 12. speed the overall rate of speed at which an object travels or moves;calculated by dividing the total distance an object travels by the total time.
  4. 13. the state in which ones object's distance from another object is getting closer or further apart
  5. 14. point a place or object used for comparison to determine if an object is in motion
  6. 16. when a moving object increases speed, decreases speed or changes direction
  7. 17. the force that one surface exerts on another surface when the surfaces come into contact with each another.
  8. 19. the force that pulls all object towards each other.
  9. 20. Friction occurs when two objects slide over each other. Example: sand on an icy sidewalk to improve footing, rubber brake pads rubbing on tire rim to slow a bike.
Down
  1. 1. the amount of space or length between two points or objects
  2. 2. this is a vector quantity that describes how far an object moves from its original position
  3. 3. forces equal forces acting on an object in opposite directions (no motion)
  4. 4. forces forces that produce a nonzero net force,which changes an objects motion (motion)
  5. 6. a push or a pull exerted on an object
  6. 7. speed in a given direction(speed with a direction)
  7. 9. the distance an object travels per unit of time
  8. 10. the force that one surface exerts on another surface when the surfaces come into contact with each other
  9. 11. friction comes into play when a body is forced to move along a surface but movement does not start (no motion)
  10. 15. the product of an objects mass and velocity
  11. 18. First Law (Inertia) an object at rest stays at rest and an object in motion stays in motion with the same velocity and in the same direction unless acted upon by an unbalanced force.
