  1. 3. The forces two objects apply to each other
  2. 4. The law of __________ of momentum states that the total momentum of a group of objects stays the same unless outside forces act on the objects
  3. 8. A push or pull on an object
  4. 11. An attractive force that exists between all objects that have mass
  5. 12. Forces acting on an object that combine and form a net force that is not zero
  6. 13. The combination of all forces acting on an object
  7. 15. Newton's law that states that if the net force acting on an object is zero, the motion of the object does not change
  8. 16. A contact force that resists the sliding motion of of two surfaces that are touching
  9. 17. Newton's law that states that for every action there is an equal and opposite reaction
  10. 18. A measure of how hard it is to stop a moving object
Down
  1. 1. Forces acting on an object that combine and form a net force of zero
  2. 2. Newton's 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
  3. 5. A push or pull on one object by another that is touching it
  4. 6. A force that one object applies to another object without touching it
  5. 7. The gravitational force exerted on an object
  6. 9. Any motion in which an object is moving along a curved path
  7. 10. In circular motion, a force that acts perpendicular to the direction of motion, toward the center of the curve
  8. 14. The tendency of an object to resist a change in its motion
  9. 19. The amount of matter in an object
