![]() Measurement of the Sidereal Day with Tracker
written by
Mario Belloni
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.
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. Additional models and programs can be found by searching ComPADRE for Open Source Physics or Tracker. Please note that this resource requires at least version 1.5 of Java (JRE).
