Circle the best answer.

1.Two equal pushes from opposite sides leave a box still. What should you write down?
  • A.There were no forces
  • B.The forces were balanced, so the box did not move
  • C.The box was too heavy
2.Before testing, a student says the car will roll furthest on tile. What is that?
  • A.A result
  • B.A prediction to check against the results
  • C.A rule that is always true
3.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
4.A car slows and stops on carpet. Which force made it stop?
  • A.Friction from the carpet, pushing against its motion
  • B.Magnetism
  • C.No force, it just ran out
5.Why roll the car three times on each floor?
  • A.One roll might be unusual, so the results are checked
  • B.Because three is a lucky number
  • C.To wear out the car
6.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
7.You want to know whether carpet slows a toy car more than tile. What must stay the same?
  • A.The floor it rolls onto
  • B.The car, the ramp and the height it starts from
  • C.Nothing at all
8.You want to know if a bigger push makes a ball roll further. How should you push?
  • A.A big push on a ball and a small push on a box
  • B.A small push, then a big push, on the same ball and floor
  • C.The same push every time
