High school students learn about parabolic motions in their physics course. They learn the theory of the motion, but how does the theory really compare to the actual motion? Does reality match theory? If not, what could account for the differences? These questions are best answered by performing experiments, analyzing the data, comparing it to the theory, and observing.
This app was developed as part of a workshop that we held for a group of high school students. The app allows you to analyze a video of a projectile motion and compare it to a theoretical curve. Start off by taking a video of yourself throwing (tossing) a ball. Then use the app to import the video, analyze, compare. It's fairly self-explanatory, but there's an instruction PDF which describes how to use the app.
This app can be used as is in a physics workshop setting, but the other purpose of this entry is to provide ideas on how to bridge theory and experiments.

Fixed a bug where the Japanese text was being garbled. Also allowed changing the display language (Japanese/English) without restarting the app.
