Uniform circular motion measurements employing a smartphone using the phyphox app and a turntable

Abstract

Abstract 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.
