The graphs on this page represent the motion of objects along a line that is the positive position axis. Notice that the motion of objects is represented by position, velocity, or acceleration graphs.
Answer the following questions. You may use a graph more than once or not at all, and there may be more correct choices than blanks. If none of the graphs is correct, answer J.
Question 12A: Pick one graph that gives enough information to indicate that the velocity is always negative.
Question 12B: Pick three graphs that represent the motion of an object whose velocity is constant (not changing).
The graphs on this page represent the motion of objects along a line that is the positive position axis. Notice that the motion of objects is represented by position, velocity, or acceleration graphs.
