Across
  1. 2. the speed and direction of an object's motion
  2. 5. the measure of the distance an object travels per unit of time
  3. 6. the gravitational force exerted on an object
  4. 9. a force that resists the sliding motion of two surfaces that are touching
  5. 11. a force that one object can apply to another object without touching it
  6. 12. an attractive force that exists between all objects in the universe that have mass
  7. 14. Newton's ________ law of motion states that when one object exerts a force on a second object, the second object exerts a force of the same size but in the opposite direction back onto the first object
  8. 15. the reaction force in a force pair that always pushes perpendicular to the object's surface
  9. 17. the process of changing position
  10. 19. the starting point you choose to describe the location or position of an object
  11. 20. a quantity that has a magnitude and direction and is often represented with an arrow
Down
  1. 1. the action and reaction forces two objects apply onto each other
  2. 3. a simple model that uses arrows to help you understand the forces acting on an object
  3. 4. Newton's ______ law of motion states that if the net force on an object is zero, the motion of the object does not change
  4. 7. the sum of all the forces acting on an object
  5. 8. a push or a pull on one object by another that is touching it
  6. 9. a region of space that has a physical quantity (such as force) at every point
  7. 10. a measure of the change in velocity during a period of time
  8. 13. an object's distance in a certain direction from a reference point
  9. 16. a push or a pull on an object
  10. 18. Newton's _______ law of motion states that the acceleration of an object is equal to the net force acting on an object divided by the object's mass
