Circle the best answer.

1.Your results show the car rolled 90 cm on tile and 30 cm on carpet. What can you conclude?
  • A.The tile slowed the car more
  • B.The carpet slowed the car more than the tile
  • C.The floors made no difference
2.What makes a forces test unfair?
  • A.Changing the push and the floor at the same time
  • B.Repeating the test
  • C.Writing down the results
3.Before testing, a student says the car will roll furthest on tile. What is that?
  • A.A rule that is always true
  • B.A result
  • C.A prediction to check against the results
4.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
5.You want to know if a bigger push makes a ball roll further. How should you push?
  • A.The same push every time
  • B.A small push, then a big push, on the same ball and floor

  • B.The height of the ramp
  • C.The car
7.A car slows and stops on carpet. Which force made it stop?
  • A.No force, it just ran out
  • B.Magnetism
  • C.Friction from the carpet, pushing against its motion
8.You want to know whether carpet slows a toy car more than tile. What must stay the same?
