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