Summary[edit]

Description
Português: Neste artigo apresentamos um sistema para aquisição de intervalos de tempo e estimativas da velocidade a partir de sensores de luz infravermelha acoplados à placa Arduíno. Devido à precisão das medidas de tempo, que apresentam incertezas da ordem de 10−4s, somos capazes de determinar a taxa de amortecimento para o pêndulo devido à resistência do ar em um regime de pequenos ângulos. Estudamos o sistema físico formado por um pequeno frasco de vidro suspenso por um fio. Este sistema foi modelado por diferentes pêndulos, como o pêndulo físico, o pêndulo simples e o pêndulo amortecido, onde discutimos sobre os limites de validade destes modelos.
