Analyzing spring pendulum phenomena with a smart-phone acceleration sensor

Abstract

This paper describes two further pendulum experiments using the acceleration sensor of a smartphone in this column (for earlier contributions concerning this topic, including the description of the operation and use of the acceleration sensor, see Refs. 1 and 2). In this paper we focus on analyzing spring pendulum phenomena. Therefore two spring pendulum experiments will be described in which a smartphone is used as a pendulum body and SPARKvue3 software is used in conjunction with an iPhone or an iPod touch, or the Accelogger4 app for an Android device.1,2 As described in Ref. 1, the values measured by the smartphone are subsequently exported to a spreadsheet application (e.g., MS Excel) for analysis.

Measurement of the magnetic field of small magnets with a smartphone: a very economical laboratory practice for introductory physics courses

“…Numerous investigations have been published on laboratory experiments in which digital cameras or webcams are used [3][4][5][6][7] , optical mice 8,9 and games consoles and their wireless devices which control the games [10][11][12][13][14] . Also the sensors of smartphones are beginning to be used to make precise measurements [15][16][17][18][19][20] . These sensors allow carrying out direct measurements of physical magnitudes if we have previously downloaded specific applications, most of which are free, that allow us to show measurements on the screen of the smartphone, store them and even do a graph with the results.…”

Smartphysics: el uso docente del Smartphone para el desarrollo de competencias transversales

“…En este trabajo pretendemos enseñar a los estudiantes de que el teléfono móvil puede ser útil también como dispositivo de medida y despertar su curiosidad e interés por utilizar este instrumento para diversas aplicaciones prácticas En la literatura científica del área de docencia de la física se pueden encontrar propuestas de experimentos con smartphones. Estas propuestas están en la misma línea que este trabajo, pero ninguna de ellas hace referencia a la implementación de estos experimentos en grupos de alumnos (Klein et al 2014;Kuhn y Vogt 2012;González y González Rebollo 2015;Huete et al 2015;Arribas Garde et al 2015;Kuhn y Vogt 2013;Sans et al 2013;CastroPalacio et al 2013;Tuset-Sanchis et al 2015;Castro-Palacio et al 2014). Solamente en algunos trabajos recientes realizados por nuestro grupo, aparecen las primeras referencias a la implementación de este tipo de experiencias con alumnos (Sans et al 2016;Cuenca-Gotor et al 2015;.…”

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

“…Specifically, the acceleration sensor of the smartphones has been used for the study of oscillations in simple and coupled oscillations at both qualitative and quantitative levels in high schools [12,13], and in universities [14,15], respectively. These works show very simple experiments where the mobile phone itself is the body under study.…”
