Abstract: The wide range and number of articles published in this column show that smartphones are very useful tools, capable of accomplishing many tasks with just a single click. They are loaded with many sensors that can be used as a tool for learning physics and performing physics classroom experiments. It has already often been described how mechanical oscillations can be analyzed in different contexts and ways with smartphones. In this article, the damping effect of a simple pendulum is studied with a smartphone hanging in different orientations. Therefore, we use the app Phyphox, which can remotely be connected to another device like a desktop or laptop computer, allowing one to access the experimental data through the connected device.
