Questions and Answers
  • 1. 
    Momentum means or is most associated with:
    • A. 

      Inertia

    • B. 

      Newton's second Law

    • C. 

      Inertia in Motion

    • D. 

      Impulse

  • 2. 
    What could be the momentum of a 1,300-kg car that moves at 4 m/s?
    • A. 

      5,200 N

    • B. 

      5,200 kg.m/s

    • C. 

      52 kg.m/s

    • D. 

      52 N

  • 3. 
    Will a large truck always have more momentum than a roller skate?
    • A. 

      No, a large truck at rest has no momentum. A moving roller skate has momentum.

    • B. 

      Yes, a large truck has greater mass than a a roller skate.

  • 4. 
    Why is falling on a floor with more give less dangerous than falling on a floor with less give?
    • A. 

      Because the floor with more give allows a greater time for the impulse that reduces the momentum of fall to zero. A greater time for a change in momentum results in less force.

    • B. 

      Because falling on a floor with more give causes less impact.

    • C. 

      Because falling on a floor with more give includes greater momentum.

    • D. 

      Because falling on a floor with less give comprises shorter time.

  • 5. 
    Read the following statement :"If no net force or net impulse acts on a system, the momentum of that system cannot change." What does it refer to?
    • A. 

      Law of Impulse

    • B. 

      Newton's 3rd Law

    • C. 

      Law of Momentum

    • D. 

      Law of Conservation of Momentum

  • 6. 
    Newton's second law states that of no net force is exerted on a system, no acceleration occurs. Does it follow that no change in momentum occurs?
    • A. 

      No, other variables can lead to the change in speed other than acceleration.

    • B. 

      Yes, because no acceleration means that no change occurs in velocity or in momentum.

  • 7. 
    A blue billiard ball is moving at speed "v" towards a red ball of the same mass standing still. Assuming it is an elastic collision, after hitting the red ball, the blue one:
    • A. 

      Bounces back.

    • B. 

      Stops.

    • C. 

      Moves along with the red ball at half "v".

    • D. 

      Moves along with the red ball at "v".

  • 8. 
    What impulse occurs when an average force of 15 N is exerted on a cart for 3.0 s?
    • A. 

      55 N.s

    • B. 

      50 N.s

    • C. 

      45 N.s

    • D. 

      40 N.s

  • 9. 
    Based on the problem above, if the mass of the cart is 5 kg and the cart is initially at rest, its final speed is equivalent to:
    • A. 

      9 m/s

    • B. 

      15 m/s

    • C. 

      20 m/s

    • D. 

      10 m/s

  • 10. 
    What is the average force that a gun exerts on a bullet shot with an impulse of 14,000 N.s? Assume it took 0.4 s for the bullet to leave the barrel.
