The Measurement of the Sidereal Day with Tracker Lab uses the Tracker video analysis tool to measure and analyze the motion stars near Polaris (the North Celestial Pole) to determine the length of the sidereal day. This exercise uses 13 still images taken 10 minutes apart of the night sky near Polaris.
Requires Tracker version 4.6 or greater.
The zip file contains the lab instructions, the series of still images that will be made into a movie, and a sample Tracker file.
Measurement of the Sidereal Day with Tracker Lab is one of several Tracker models used to incorporate computational and video analysis techniques in introductory astronomy. Tracker, a video analysis program with dynamical modeling, is an Open Source Physics tool.
