MHS em vídeo análise através do Tracker: sistema massa mola vertical sob ação da força gravitacional

Abstract

It goes without saying, nor is the idea that most high school students have great difficulties in learning physics concepts is new. These difficulties, however, can be minimized with the use of Information and Communication Technologies (ICT). Within this perspective, we find numerous simulation and/or analysis software dedicated to facilitating the teaching of physics, and for having free access, translated into Portuguese, widely spread throughout the world, easy to understand, rich in resources and other attractions, Tracker analysis and modeling software was chosen to anchor our study. Thus, this work is dedicated to exploring, at high school level, aspects of simple harmonic movement, especially the vertical spring mass system under gravity in video analysis through the Tracker, in order to determine the elastic constant of springs, as well as their behavior when associated in series and parallel, bringing in detail from the recording of the video object of the study, entering the steps required for its correct analysis, presentation of its hourly equations, energy balance, graphs drawn by the Tracker, and finally, detailing the analogy between the MHS and the uniform circular movement as well as the equivalence of the horizontal and vertical spring mass system.
