Across
  1. 3. a push or a pull on one object by another object that is touching it.
  2. 8. the speed and the direction of a moving object.
  3. 11. the forces two objects apply to each other.
  4. 13. the combination of all the forces acting on an object.
  5. 16. the force that pushes perpendicular to the object’s surface.
  6. 17. a region of space that has a physical quantity (such as a force) at every point.
  7. 19. an object’s distance and direction from a reference point.
  8. 22. the difference between the initial, or starting, position and the final position.
  9. 23. when colliding objects bounce off each other.
Down
  1. 1. a force that one object applies to another object without touching it.
  2. 2. the process of changing position.
  3. 4. law that states that the acceleration of an object is equal to the net force exerted on the object divided by the object’s mass.
  4. 5. contact force that resists the sliding motion of two surfaces that are touching.
  5. 6. a push or a pull on an object.
  6. 7. a simple model to understand what will happen to an object due to a force.
  7. 9. when an object applies a force on another object, the second object applies a force of the same strength on the first object but the force is in the opposite direction.
  8. 10. a quantity that has both magnitude and direction.
  9. 12. an object at rest will stay at rest, and an object in motion will stay in motion unless a force acts on the object.
  10. 14. the starting point you choose to describe the location, or position, of an object.
  11. 15. the gravitational force exerted on an object.
  12. 18. a measure of the change in velocity during a period of time.
  13. 20. an attractive force that exists between all objects that have mass.
  14. 21. a measure of the distance an object travels in a given amount of time.
