  1. 1. exists when an object from the external world touches a system exerting force on it
  2. 6. a specific name for the force that a string or rope exerts
  3. 10. vector quantity that relates the mass of an object to the gravitational force it experiences at a given location
  4. 14. a push or pull
  5. 15. set of two forces that are in opposite directions, have equal magnitudes, and act on different objects
  6. 16. important objects of interest with respect to how the force affects motion
  7. 17. a physical representation that shows the forces acting on a system
Down
  1. 2. the constant velocity that is reached when the drag force equals the force of gravity
  2. 3. the vector sum (could be adding or subtracting)of all the forces on an object
  3. 4. the gravitational force experienced by that object
  4. 5. the force exerted by a fluid on an object opposing motion through fluid
  5. 7. acceleration is proportional to the net force and inversly proportional to the mass of the object being accelerated
  6. 8. the normal force exerted by a surface on an object, which can differ from the objects true weight due to acceleration
  7. 9. an object at rest will stay at rest ect.
  8. 11. the perpendicular contact force that a surface exerts on another surface
  9. 12. if the net force on an object is zero
  10. 13. forces exerted without touching
  11. 15. the tendency of an object to resist change in velocity
