Circle the best answer.

1.Why roll the car three times on each floor?
  • A.One roll might be unusual, so the results are checked
  • B.To wear out the car
  • C.Because three is a lucky number
2.A car slows and stops on carpet. Which force made it stop?
  • A.Magnetism
  • B.Friction from the carpet, pushing against its motion
  • C.No force, it just ran out
3.You test pushing a box from one side, then from both sides at once. What are you testing?
  • A.What color works best
  • B.How heavy the box is
  • C.How the direction of the forces changes the motion
4.Before testing, a student says the car will roll furthest on tile. What is that?
  • A.A result
  • B.A rule that is always true
  • C.A prediction to check against the results
5.What should you measure to see how much each floor slowed the car?
  • A.How loud the car is
  • B.How far the car rolls before it stops
  • C.The color of the car
6.What makes a forces test unfair?
  • A.Repeating the test
  • B.Changing the push and the floor at the same time
  • C.Writing down the results
7.In the carpet and tile test, what is the one thing you change?
  • A.The height of the ramp
