2. In Logger Pro, load the MotionVelocity experiment (File/Open/MotionVelocity) to test your prediction. Choose a starting position and stand at that point. Start the data collection by clicking "collect" button. When you hear the Motion Detector begin to click, walk in such a way that the graph of your motion matches the target graph on the screen. It will be more difficult to match the velocity graph than it was for the distance graph.

3. Now attempt to replicate the second graph shown here (click graph here for enlarged view).
