Use Physics Gizmo to Collect Physics Data
Physics Gizmo is a free Android app developed by a science teacher for science teachers and students. The purpose of Physics Gizmo is to provide a tool that students can use to accurately record motion data. The app can be synced to a Blue Tooth to record pendulum timing and acceleration data. Your recorded data can be exported to Google Docs and Google Fusion Tables.
You can read all about the development of Physics Gizmo and ideas for educational uses on Phil Wagner’s (the developer) blog Broken Airplane.
