  1. 4. (da) 10
  2. 6. Newton's ____ of motion states "When dealing with an object for which all existing forces are not balanced, the acceleration of that object, as produced by the net force, is in the same direction as the net forced directly proportional to the magnitude of the net force, and is inversely proportional to the object's mass."

  5. 13. A unit of work is called a newton-meter or ____.
  6. 16. ____ is performed on an object when there is an applied force that is along the same line of movement and is also measured in joules (j).
  7. 17. ____ is the rate of change of velocity.
  8. 19. Newton's ____ of motion states that "For every action, there is an equal and opposite reaction."
