Circle the best answer.

1.You test pushing a box from one side, then from both sides at once. What are you testing?
  • A.What color works best
  • B.How heavy the box is
  • C.How the direction of the forces changes the motion
2.You want to know whether carpet slows a toy car more than tile. What must stay the same?
  • A.The car, the ramp and the height it starts from
  • B.Nothing at all
  • C.The floor it rolls onto
3.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
4.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.The box was too heavy
  • C.There were no forces
5.You want to test whether two pushes move a box further than one. What do you change?
  • A.The number of pushes
  • B.The box
  • C.The floor
6.What should you measure to see how much each floor slowed the car?
  • A.How far the car rolls before it stops
  • B.How loud the car is
  • C.The color of the car
7.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
8.What makes a forces test unfair?
  • A.Repeating the test
  • B.Changing the push and the floor at the same time
  • C.Writing down the results
