The paper Innovative Uses of Video Analysis describes several new video analysis and computational modeling experiments in mechanics, optics and thermal physics made possible by Tracker, a free, open-source video analysis tool. Experiments include viewing and analyzing 2d collisions in a center of mass reference frame, modeling the air resistance force on falling cupcake cups, measuring thermal expansion using single-slit diffraction, and analyzing the emission spectra of lasers, gases, fluorescent dyes and fluorescent lamps.
