Abstract:
Augmented Reality (AR) allows students to overlap the reality with additional information or indirect observation through a technological device of the physics of reality. The aim of this paper is to present the use of Tracker for learning a classical study in the coupled oscillations of two coupled pendula. We present the study of the symmetric normal mode, antisymmetric normal mode and the beats phenomena for the oscillations of coupled pendula. Measurements are made by recording the experiment with a digital camera and using Tracker software, a video analysis and video modeling tool to process and get information from recorded videos. With this set-up, detailed comparisons may be made between theoretical calculations and measurements, with focus on several relevant concepts, such as the oscillation period for the symmetrical and antisymmetrical mode, the elastic coupling spring constant and the beats period dependence on the position of the spring coupling. Such way, the experiment based on video analysis of the experiment is used to focus on key concepts and to motivate students in their exploratory work and also to stimulate autonmous investigation.
