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