Examples and difficulties A1 González Delgado, Manuel Ángel A1 Gómez Bravo, Alfonso A1 González Rebollo, Miguel Ángel K1 Physics K1 Laboratory K1 Experiments K1 Smartphones K1 Teaching AB In this paper we describe a classical experiment with an air track in which smartphonesare used as experimental devices to obtain physical data. The proposed experiment allowsusers to easily observe and measure relationships between physical magnitudes, conservation of momentum in collisions and friction effects on movement by utilizing the users’own mobile devices.
