Pêndulo Simples: Tracker x Phyphox

摘要: Within didactical purposes, the measurement of local gravitational constant using Phyphox App method has no significant gain in accuracy when compared with traditional method. To achieve this conclusion, an experiment which smartphone was used as a pendulum, running Phyphox, filmed. The period movement obtained from two independent sources: data given by Phyhpox and video analysis, performed software Traker. Then, set up without cellular to show big influence human operator chronometer (traditional method) comparison Traker methodology, we believe is most accurate. Moreover, case, it possible see unexpected interesting behavior pendulum during approximately 24% its periodic movement. effect so prominent that became clear that, rigorous point view, simple mathematical model cannot be applied all have our tests.
