An object falls freely from rest in a vacuum. The graph shows the variation with time t of the velocity v of the object. [Figure 11.1] Which graph, using the same scales, represents the object falling in air?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
AGraph A: v vs t, linear increase from 0.
BGraph B: v vs t, curved increase, concave up from 0, flattening out.
CGraph C: v vs t, curved increase, concave down from 0, flattening out to a terminal velocity.
DGraph D: v vs t, curved increase, concave up then down, reaching a peak then decreasing.
✓ Correct answer
C: Graph C: v vs t, curved increase, concave down from 0, flattening out to a terminal velocity.
