A physical pendulum experiment with Lego, Phyphox and Tracker

Abstract

In this study, a physical pendulum experiment, which is one of the basic experiments at the high school level, was carried out using Lego bricks and smartphones (Phyphox application) that students are familiar with in their daily lives. In this way, it is aimed to provide an example to students and teachers about low-cost, theory-compatible experiments that students can perform on their own in out-of-school environments, especially in mechanics. In addition, another aim of the study was to record the experiment on video and analyse it with a video analysis program (Tracker) and to compare the two methods (using a smartphone application and a video analysis program) in terms of results and usability.
