Across
  1. 4. quantity that is defined as the rate at which an object changes its velocity.
  2. 9. Any object that is being acted upon only by the force of gravity
  3. 10. for example is what causes a ball to go faster and farther when rolling than a sliding book
  4. 11. amount of matter that is present in an object
  5. 12. quantity that refers to "how much ground an object has covered" during its motion
  6. 13. the force that opposes a motion that takes place within fluids or in between fluids
  7. 16. a set of coordinates that can be used to determine positions and velocities of objects in that frame
  8. 20. vector sum of all the forces that act upon an object.
  9. 22. quantities that are fully described by both a magnitude and a direction.
  10. 23. the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object
  11. 24. force of gravity that acts on an object.
  12. 25. the force exerted by a surface as an object moves across it or makes an effort to move across it.
Down
  1. 1. quantities that are fully described by a magnitude (or numerical value) alone
  2. 2. For every action, there is an equal and opposite reaction
  3. 3. when the surfaces of two objects are at rest relative to one another and a force exists on one of the objects to set it into motion relative to the other object.
  4. 5. results when an object slides across a surface.
  5. 6. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force
  6. 7. this is the weight of the object.
  7. 8. quantity that refers to "how far out of place an object is
  8. 14. any place or point or coordinate which you take as standard with respect to which you will standardize other phenomena relatively.
  9. 15. quantity that refers to "the rate at which an object changes its position
  10. 17. push or pull upon an object resulting from the object's interaction with another object.
  11. 18. quantity that refers to "how fast an object is moving.
  12. 19. The change in position in an object over time.
  13. 21. mass in motion
