This paper describes an experiment on uniform circular motion, carried out in a second year class of the High School ‘E. Fermi’ of Ragusa (Sicily/Italy), employing an old turntable and a smartphone using the phyphox app. Data analysis allowed us to confirm that the motion is maintained uniform for all three nominal values of the turntable frequencies. We were also able to measure angular accelerations, in both the switch on and final stop phases. Thanks to the easy availability of the equipment used, the activity can also be proposed as Hands up teaching, to be carried out during extracurricular hours in either single or group work.

使用phyphox应用程序和转盘使用智能手机进行均匀圆周运动测量

本文介绍了在高中'E的第二年级上进行的匀速圆周运动实验。拉古萨（意大利西西里岛/意大利）的费米（Fermi'），使用了一个旧的转盘和一个使用phyphox应用程序的智能手机。数据分析使我们能够确认转盘频率的所有三个标称值的运动均保持一致。在接通阶段和最终停止阶段，我们还能够测量角加速度。由于所使用的设备容易获得，该活动也可以提议为动手教学，可以在课外时间以单人或小组作业的形式进行。
