In the past two decades, several computer software tools have been developed to investigate the
motion of moving bodies in physics laboratories. In this article we report a Matlab based video
tracking library, PhysTrack, primarily designed to investigate kinematics. We compare PhysTrack with
other commonly available video tracking tools and outline its salient features. The general
methodology of the whole video tracking process is described with a step by step explanation of
several functionalities. Furthermore, results of some real physics experiments are also provided to
demonstrate the working of the automated video tracking, data extraction, data analysis and
presentation tools that come with this development environment. We believe that PhysTrack will be
valuable for the large community of physics teachers and students already employing Matlab.
