The velocity–time graph for an accelerating object that is traveling in a straight line is shown below.

Which of the following is the change in displacement of the object in the first 5.0 seconds?

A. 25.0 m
B. 12.5 m
C. 5.0 m
D. 1.0 m

B

There were a few comments on the G2 forms about the use of the term “displacement”. Displacement is generally understood as the vector from a fixed point to the position of a particle. As the particle moves, the position and hence the displacement vector, changes. Thus it is perfectly correct to ask about the “change in the displacement”.
