This study investigates the motion of a falling smartphone under the influence of air drag using acceleration data collected by its built-in accelerometer. The proper acceleration profiles demonstrate the suitability of the turbulent drag model in capturing the motion dynamics during both upward and downward phases. This approach provides an effective and accessible method for exploring fluid dynamics concepts in an educational context.
