Studying Circular Motion with an AI-Generated Smartphone Physics Lab
arXiv:2607.28352
The paper presents a fully customized, browser‑based smartphone lab for studying uniform and uniformly accelerated circular motion, created solely through natural‑language prompts to an AI assistant, and validates the sensor data against video analysis.
Abstract
Smartphones have become a standard measurement instrument in the physics laboratory. Theirbuilt-in accelerometers, gyroscopes, magnetometers, and cameras have been used to investigate a wide range of phenomena in mechanics, and rotational motion in particular has proven especially well-suited to smartphone-based experiments. A recurring limitation, however, is that most experiments rely on precompiled sensor apps whose interfaces cannot be tailored to a specific activity, and until recently creating customized smartphone laboratories required programming knowledge beyond what most physics teachers possess. Following the approach, we recently introduced for acoustic experiments,10 in this paper we show that a fully customized, browser-based rotation laboratory can be generated entirely through natural-language prompting of an AI assistant, with no manual coding. We use it, together with a simple rotating platform, to characterize both uniform circular motion (UCM) and uniformly accelerated circular motion (UACM), and we validate the sensor measurements against independent video analysis with Tracker.
