Circle the best answer.

1.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.What color works best
  • C.How the direction of the forces changes the motion
2.Two equal pushes from opposite sides leave a box still. What should you write down?
  • A.There were no forces
  • B.The box was too heavy
  • C.The forces were balanced, so the box did not move
3.A car slows and stops on carpet. Which force made it stop?
  • A.No force, it just ran out
  • B.Friction from the carpet, pushing against its motion
  • C.Magnetism
4.What should you measure to see how much each floor slowed the car?
  • A.The color of the car
  • B.How far the car rolls before it stops
  • C.How loud the car is
5.Before testing, a student says the car will roll furthest on tile. What is that?
  • A.A rule that is always true
  • B.A prediction to check against the results
  • C.A result
6.You want to test whether two pushes move a box further than one. What do you change?
  • A.The floor
  • B.The number of pushes
  • C.The box
7.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
8.In the carpet and tile test, what is the one thing you change?
  • A.The floor the car rolls onto
  • B.The car
  • C.The height of the ramp
