26. Question Column 3-300 If several people push a stalled car, what force is overcome at the moment the car begins to move?

27. Answer Column 3-300 friction

28. Question Column 3-400 In our labs which two forces can make an object move faster?

29. Answer Column 3-400 Applying more force, Raise the ramp, Having less weight

30. Question Column 3-500 TrialWeightNewtonsSpeed 1500 g1035 m/sec 21000 g10 In the experiment above, what is the speed of the second trial? Why do you think so?

31. Answer Column 3-500 The speed should be half or 17.5 m/sec because if you double the weight, you cut the speed in half.
