The resultant force acting on an object is slowly increased. Which graph could show the variation with time t of the momentum p of the object? [Figure 7.1]
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 showing momentum p increasing with time t, initially with an increasing gradient, then a decreasing gradient, then constant.
BGraph showing momentum p increasing with time t, initially with a constant gradient, then an increasing gradient, then constant.
CGraph showing momentum p increasing linearly with time t.
DGraph showing momentum p increasing with time t, initially with an increasing gradient, then a decreasing gradient, then decreasing.
✓ Correct answer
B: Graph showing momentum p increasing with time t, initially with a constant gradient, then an increasing gradient, then constant.
