Leis de Newton: uma proposta experimental de baixo custo para o ensino de Física

Abstract

This work aims to develop a methodological proposal for teaching Newton’s Laws, using low cost experiments easily applicable in public school classrooms. The research seeks to overcome limitations of traditional physics teaching, thus promoting meaningful learning, based on student interest and protagonism. It is an applied, qualitative investigation focused on the elaboration and analysis of the ”Balloon-Rocket” experiment, a simple resource that effectively illustrates these physical principles. To examine the movement, the Tracker software, a free video analysis and modeling tool, was used, allowing the collection of time (t) and position (x) data. It was concluded, therefore, that integrating accessible experimental practices and active methodologies with the use of technologies such as the Tracker software is a viable and effective strategy. This approach fosters a solid conceptual understanding and stimulates investigative thinking, making physics learning more dynamic, critical, and contextualized.
