Studio sperimentale della caduta di una sfera in aria, con le possibilità offerte dalle nuove tecnologie

In this article we describe on-line experiments involving spheres falling in air, using graphic calculators connected to CBL units and distance sensors, which permit a quick acquisition and analysis of the experimental data. Comparing the motion graphs of a billiard ball and a light polystyrene sphere, a model for the fall in air is developed and verified by numerical methods.
