Analyzing Complex Motion To begin your activity, open this Tracker experiment: Car Round Trip.

Click play to watch the video. The other video controls allow you to rewind the video or step forward or backward one frame at a time.

Part A
Describe what you see in the video.
Part B
It’s time to get a little more specific. Based on the velocity (vx) graph for the car and the velocity data in the table, divide the total motion of the car into rough time periods that tell a different “chapter” of the story for this car trip. In each of these time periods, the car’s velocity will be notably different from the previous period. Enter a brief description of the car’s motion in each period. The first one is done for you. Use it as an example to identify and describe the remaining time periods. Note: You can define as many periods as you think appropriate.
Part C
Now, for each time period, look at the graphs of x, vx, and ax. Briefly describe what is happening for each of these variables during your identified time periods. To view any of these graphs in detail, double-click the graph. You’ll be able to view it in the Data Tool window.
