  2. 3. An object would ___ if the force applied is in the same direction as the object's motiona
  3. 4. Unit of measure for force
  4. 7. The point in an object that moves as if all of its mass were concentrated in one spot
  5. 8. Occurs any time an object speeds up, slows down or changes direction
  6. 9. The acceleration of an object can be ___ if the object's mass and net force are known
  7. 11. Forces acting on an object that allow the object to change its acceleration
  8. 14. Force that is always perpendicular to the motion of an object that is moving in a circle
  9. 16. The force of gravity between two objects depends on the masses of the objects and the ___ between them

  4. 10. If the net force acts at an angle to the direction of an object's motion then the object will move in a ___
  5. 12. A moving object slows down if the net force is ___ to its motion
  6. 13. Describes how fast an object is moving and in what direction
  7. 15. All forces exerted on an object
