Resumen de Smartphones and Gravitational Acceleration II: Applications

Meryem Berrada, Joshua A. Littleton, Richard Secco

• The exercises described here conveniently exploit the built-in acceleration sensors in smartphones, devices that are becoming ubiquitous if not essential items for most students. This allows each student to have the opportunity for a hands-on experience and to collect their own data, reduces preparation time, and greatly reduces cost by removing the need of purchasing a gravimeter to perform the same or similar tasks in gravity surveys. These exercises further demonstrate the educational value of using smartphones as scientific tools and that freely available accelerometer software applications operate with acceptable tolerance. The differences between accelerometers placed in smartphones and gravimeters are further discussed in the companion paper, “Part 1: Smartphone Applications for Gravitational Acceleration Surveys.”
