Using a smartphone acceleration sensor to study uniform and uniformly accelerated circular motions

Abstract

The acceleration sensor of a smartphone is used for the study of the uniform and uniformly accelerated circular motions in two experiments. Data collected from both experiments are used for obtaining the angular velocity and the angular acceleration, respectively. Results obtained with the acceleration sensor are in good agreement with alternative methods, like using video recordings of both experiments and a physical model of the second experiment.
