In this activity, students will be introduced to the CBR 2 motion sensor and the Vernier DataQuest™ app. They will collect and analyze both linear and non-linear data.

Work in groups of two. One person will operate the handheld and also point the CBR 2 toward the torso of the other person, the “walker.” The walker should be standing approximately two meters from the motion sensor. The walker will walk slowly toward the motion sensor at a constant rate for five seconds.
