Circle the best answer.

1.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
2.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 floors made no difference
  • C.The carpet slowed the car more than the tile
3.You test pushing a box from one side, then from both sides at once. What are you testing?
  • A.How heavy the box is
  • B.How the direction of the forces changes the motion
  • C.What color works best
4.Before testing, a student says the car will roll furthest on tile. What is that?
  • A.A prediction to check against the results
  • B.A rule that is always true
  • C.A result
5.What makes a forces test unfair?
  • A.Writing down the results
  • B.Repeating the test
  • C.Changing the push and the floor at the same time
6.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.The same push every time
  • C.A small push, then a big push, on the same ball and floor
7.Two equal pushes from opposite sides leave a box still. What should you write down?
  • A.The forces were balanced, so the box did not move
  • B.There were no forces
  • C.The box was too heavy
8.In the carpet and tile test, what is the one thing you change?
  • A.The height of the ramp
  • B.The car
