Teaching Physics by Arduino during COVID-19 Pandemic: The Free Falling Body Experiment

Abstract

One of the difficulties related to the COVID-19 pandemic is the shifting from face-to-face to distance teaching. Both schools and universities had suddenly to organize on-line lectures. To perform laboratory practice even in this period, easily accessible materials, smartphones physics apps, on-line tools and devices can be used. In this paper a method to measure the gravitational acceleration studying the free falling body using Arduino board is presented.
