Physics Education using a Smartphone Accelerometer
arXiv:1012.3416
Abstract
Described is an experiment in which a smartphone was caused to move at steady state in a vertical plane, on a path that was nearly circular. During a time interval of data acquisition that encompassed multiple orbits, the acceleration of the phone was measured by means of its internal accelerometer. A subsequent analysis of the data that was collected shows reasonable agreement between experiment and a simple theory of the motion.
