Using digital video analysis in introductory mechanics projects

During the first semester of our calculus-based introductory physics course sequence, students work in small groups on mechanics projects. Many teams choose digital video analysis for projects involving mechanics. We discuss the management of collaborative projects and schemes for critiquing collaborative papers and assigning individual grades. We also describe some of the more interesting projects. Finally, we offer some advice on how to find the information needed to create good digital video movies.
