Tracker is an image and video analysis package and modeling tool that is built upon the Open Source Physics Java code library.
Features include object tracking with position, velocity and acceleration overlays and graphs, special effect filters, multiple reference frames, calibration points and line profiles for analysis of spectra and interference patterns. It is designed to be used in introductory college physics labs and lectures.
I was unable to upload a file from my computer or from a youtube link. More clear instructions are needed for how to use the web-based app to upload a video for analysis.
This program is great! Yes you can not save but it allowed me to do something I as a physics teacher couldn't. If you are physics instructor get this--it works and is fun. Thank you.
Been using tracker for years in my physics classes. Being able to use it on a Chromebook is going to be cool. Seems like everything that I normally use is working... except AutoTrack. Not sure it it is a multi-window issue.
