A contribuição da videoanálise em uma sequência didática para determinar os efeitos da resistência do ar sobre um paraqueda

Abstract

In this work, we present the elaboration of a didactic sequence for teaching the applications of Newton's Laws, in particular, the special cases of air resistance, acting on a parachute. To this end, video analysis was explored through the Tracker software, which allows students to become central and active agents in experimental activities, by filming the experiments, obtaining and processing the respective data. The sequence was produced with the Theory of Meaningful Learning as a theoretical framework. By judiciously using the technology available to the student, a more effective learning becomes possible and enhances an education that seeks to emancipate and empower the student, especially when it combines academic quality and free technologies. In this sense, this work provides students with theoretical foundations through significant experimental activities in physics classes mediated by free educational technologies that present, at the same time, quality, flexibility of use and low cost, so that they are compatible with the reality of Brazilian education.
