Newtons Third Law Of Motion

Questions and Answers
  • 1. 
    For every action, there is an equal and opposite reaction.
    • A. 

      True

    • B. 

      False

  • 2. 
    According to Newton's third law, for every action force there is an equal (in size) and opposite (in direction) reaction force. Forces always come in pairs - known as "action-reaction force pairs."
    • A. 

      True

    • B. 

      False

  • 3. 
    Describe the other force in the action-reaction force pair.
    • A. 

      The glove pushes the baseball rightward.

    • B. 

      The glove pushes the baseball upward.

    • C. 

      The glove pushes the baseball downward.

    • D. 

      None of the above.

  • 4. 
    Describe the other force in the action-reaction force pair.
    • A. 

      Pin pushes bowling ball rightward.

    • B. 

      Pin pushes bowling ball upward.

    • C. 

      Pin pushes bowling ball downward.

    • D. 

      None of the above.

  • 5. 
    Describe the other force in the action-reaction force pair.
    • A. 

      Balloon wall pushes enclosed air particles inwards.

    • B. 

      Balloon wall pushes enclosed air particles outwards.

    • C. 

      Balloon wall pushes enclosed air particles upwards.

    • D. 

      None of the above.

  • 6. 
    According to Newton's third law,The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.  
    • A. 

      True

    • B. 

      False

  • 7. 
    The Law of Conservation of Momentum states that
    • A. 

      All the momentum in a system before a reaction is greater than the momentum after a reaction.

    • B. 

      All the momentum in a system before a reaction is less than the momentum after a reaction.

    • C. 

      All the momentum in a system before the reaction is the same as all the momentum after the reaction.

    • D. 

      All the momentum in a system before a reaction is lost during the reaction so none is left following the reaction.

  • 8. 
    Johnny hits sally with a kickball while playing dodgeball in gym class.  The momentum that he hits her with is the same amount of momentum that the ball has when it bounces off sally... In other words, no momentum was lost in the reaction. 
    • A. 

      True

    • B. 

      False

  • 9. 
    Knowing Newton's Third Law of Motion and the Law of Conservation of Momentum, would you rather ride in a modern car that is light and small but has lots of safety standards built in or a big, heavy older car that lacks some of the safety standards (remember the collision video)?
    • A. 

      Newer car with safety standards because they are built to withstand the momentum of the collison.

    • B. 

      Older car without safety standards because the huge mass of the older cars means I will be safer in a collision.

    • C. 

      Newer car with safety standards because the gas mileage is better so less chance to get into an accident.

    • D. 

      Older car without safety standards because the gas mileage is so high I wouldn't be able to afford the gas to drive in it much, so less chance to get into an accident.

  • 10. 
    Momentum is not always conserved - some could be lost in the system.
    • A. 

      True

    • B. 

      False
