GRAPHING ASSOCIATION 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 second to 8 second, (b) 8 second to 12 second, and (c) 12 second to 20 second. 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?3. 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?

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 85, (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? lb) How do the signs of the values (positive, zero, or negative] relate to each other? 3. 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
