  • C.A rule that is always true
2.A car slows and stops on carpet. Which force made it stop?
  • A.Magnetism
  • B.No force, it just ran out

4.Your results show the car rolled 90 cm on tile and 30 cm on carpet. What can you conclude?
  • A.The floors made no difference
  • B.The tile slowed the car more
  • C.The carpet slowed the car more than the tile
5.Why roll the car three times on each floor?
  • A.Because three is a lucky number
