Resumen We report the study of an oscillating pendulum under various damping conditions. A smartphone was used as a pendulum and, at the same time, as a data recorder. Results show that the smartphone is an effective and reliable tool for performing educational activities, providing students with a variety of ways to learn new content and physical concepts. It offers the opportunity to carry out experiments in the classroom, laboratory, or at home.

Resumen This article reports on characteristics that describe movement in one dimension under two different conditions: movement horizontally and movement on an inclined plane. We used a magnetometer built into a smartphone to obtain and record data through a software application. The Arduino Uno board and the HC-SR04 Ultrasonic distance sensor validate the feasibility of the smartphone magnetometer technique, and results show that it has a high degree of reliability.
