- The use of new technologies is a useful tool to approach the students to fundamental Physics problems. In particular, smartphones are the most common devices among the young people and may be suitable in multitude of basic Physics experiments. Here, we report the use of the accelerometer sensor of a smartphone to visualize and demonstrate the parallel-axis theorem in a torsion pendulum. The study of the moment of inertia using a torsion pendulum is a typical example in the first courses of fundamentals of Physics. Several works have exposed different simple approaches to this system in order to make it attractive to the students. On the other hand, a recent trend to use the Smartphone's sensors has arisen in basic Physics lab practices, so the students work with instruments that are familiar to them. We attached a smartphone to a torsion pendulum in order to collect the acceleration time series and thus, i) to determine the stiffness of the spring, ii) to demonstrate the parallel-axis theorem and iii) to describe the Harmonic oscillations produced.
