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