  • 1. 
    A student wants to set up an experiment to determine the effect of a net force on an object’s acceleration. To do this, she should
    • A. 

      Vary the force acting on the object and the mass of the object at the same time

    • B. 

      Vary the mass of the object, but not the force acting on the object

    • C. 

      Vary the force acting on the object, but not the object’s mass

    • D. 

      Keep both the force acting on the object and the mass of the object constant as it rolls along a horizontal surface

  • 2. 
    A 2 kg block is dropped from the roof of a tall building at the same time a 6 kg ball is thrown horizontally from the same height. Which statement best describes the motion of the block and the motion of the ball? 
    • A. 

      The 2 kg block hits the ground first because it has no horizontal velocity

    • B. 

      The 6 kg ball hits the ground first because it is round

    • C. 

      The 6 kg ball hits the ground first because it has more mass

    • D. 

      The block and the ball hit the ground at the same time because they have the same vertical acceleration

  • 3. 
    A student is holding a book that has a weight of 20N in her hand while sitting in a chair. She claims that the book must be attracting Earth with a force of 20 N. Her claim must be
    • A. 

      False because books do not attract objects

    • B. 

      False because Earth is much larger than the book

    • C. 

      True because the book has more inertia than Earth

    • D. 

      True due to Newton’s third law of motion

  • 4. 
    Which diagram of a 5 kg mass resting on a table correctly represents the force (not mass!) of the table on the mass?
    • A. 

      Image a is correct

    • B. 

      Image b is correct

    • C. 

      Image c is correct

    • D. 

      Image d is correct

  • 5. 
    A cart is rolling along a frictionless horizontal surface. Which of the following describes the motion of the cart as it continues to roll along the surface?
    • A. 

      The cart will slow down as it runs out of forward force

    • B. 

      The cart will continue to roll with constant speed

    • C. 

      The cart will continue to roll with constant speed only if it is rolling downhill

    • D. 

      The cart will slow down as it uses up its speed

  • 6. 
    Which object has the most inertia?
    • A. 

      A 0.001 kg bumblebee traveling at 2 m/s

    • B. 

      A 0.1 kg baseball traveling at 20 m/s

    • C. 

      A 5 kg bowling ball traveling at 3 m/s

    • D. 

      A 10 kg tricycle at rest

  • 7. 
    Two students have a tug-of-war on a smooth gym floor. One student has a mass of 70 kg and is wearing socks but no shoes. The other student has a mass of 60 kg and is wearing athletic shoes. The student most likely to win will be
    • A. 

      The 60 kg student because he can pull harder than the 70 kg student

    • B. 

      The 70 kg student because he can pull harder than the 60 kg student

    • C. 

      The 60 kg student because he experiences greater frictional force with the floor

    • D. 

      The 70 kg student because he experiences a greater frictional force with the floor

  • 8. 
    A stone with an initial velocity of zero is dropped from a bridge above a river. After 3 s, the stone strikes the water below the bridge. Approximately how fast is the stone traveling when it strikes the water?
    • A. 

      10 m/s

    • B. 

      20 m/s

    • C. 

      30 m/s

    • D. 

      45 m/s

  • 9. 
    If the sum of all forces acting on a moving object is zero, the object will
    • A. 

      Continue moving with constant speed

    • B. 

      Slow down and stop

    • C. 

      Change the direction of its motion

    • D. 

      Either speed up or slow down

  • 10. 
    A soccer ball is kicked across a field. After it is no longer touching the player's foot, the ball continues to move because
    • A. 

      No force is needed for the ball to keep moving at a constant speed

    • B. 

      The force from the foot continues to push the ball forward, but eventually runs out

    • C. 

      There is a force of motion that keeps the ball going
