1. How well do the average and instantaneous velocities that you calculated agree with each other? 2 Separate the graphs into three sections: (a) 0 s to 8s, (b) 8 s to 12 s, and (c) 12 s to 20 s. For each of these three time periods, compare all three graphs in the following ways. (a) How do the shapes of the graphs (curved, straight, horizontal) relate to each other? (b) How do the signs of the values (positive, zero, or negative) relate to each other? 1 Under what circumstances can the van be moving but have a zero acceleration?

Analyze and Conclude
1. How well do the average and instantaneous
velocities that you calculated agree with
each other?
2 Separate the graphs into three sections: (a) 0 s
to 8s, (b) 8 s to 12 s, and (c) 12 s to 20 s. For
each of these three time periods, compare all
three graphs in the following ways.
(a) How do the shapes of the graphs (curved,
straight, horizontal) relate to each other?
(b) How do the signs of the values (positive,
zero, or negative) relate to each other?
1 Under what circumstances can the van be
moving but have a zero acceleration?
4 Under what circumstances is the sign of
the velocity the same as the sign of the
acceleration?
5. What general statement can you make about
the motion of the van when the direction of
the acceleration vector is opposite to the
direction of the velocity vector?
