Questions and Answers
  • 1. 
    Mac and Tosh are arguing in the cafeteria. Mac says that if he flings the Jell-O with a greater speed it will have a greater inertia. Tosh argues that inertia does not depend upon speed, but rather upon mass. Who do you agree with?
    • A. 

      Mac

    • B. 

      Tosh

    • C. 

      None of the above.

  • 2. 
    Supposing you were in space in a weightless environment, would it require a force to set an object in motion?
    • A. 

      Yes.

    • B. 

      No.

    • C. 

      None of the above.

  • 3. 
     If the forces acting upon an object are balanced, then the object
    • A. 

      Must not be moving.

    • B. 

      Must be moving with a constant velocity.

    • C. 

      Must not be accelerating.

    • D. 

      None of these.

    A group of physics teachers is taking some time off for a little putt-putt golf. The 15th hole at the Hole-In-One Putt-Putt Golf Course has a large metal rim that putters must use to guide their ball towards the hole. Mr. S guides a golf ball around the metal rim When the ball leaves the rim, which path (1, 2, or 3) will the golf ball follow?
    • A. 

      1

    • B. 

      2

    • C. 

      3

    • D. 

      None of the above.

  • 5. 
    __________ is the tendency of an object to resist changes in its state of motion.
  • 6. 
    ______________ states that "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."
  • 7. 
    To determine if the forces acting upon an object are balanced or unbalanced, an analysis must first be conducted to determine what forces are acting upon the object and in what direction.
    • A. 

      True

    • B. 

      False

  • 8. 
    Imagine a place in the space far from all gravitational and frictional influences. Suppose that you visit that place (just suppose) and throw a rock. The rock will
    • A. 

      Gradually stop.

    • B. 

      Continue in motion in the same direction at constant speed.

    • C. 

      Will not move.

    • D. 

      None of the above.

  • 9. 
     A bowling ball is rolling across the floor with a speed of 4 m/s. How much net force is required to keep the object moving at this speed and in this direction (assume no friction or gravity is present)?
    • A. 

      0 N

    • B. 

      1 N

    • C. 

      10 N

    • D. 

      None of the above.

    Fred spends most Sunday afternoons at rest on the sofa, watching pro football games and consuming large quantities of food. If he does this for several months what effect (if any) does this practice have upon his inertia?
    • A. 

      Fred's inertia stays the same!

    • B. 

      Fred's inertia will decrease!

    • C. 

      Fred's inertia will increase!

    • D.
