Uso della simulazione per lo studio del moto in sistemi di riferimento diversi

It is well known that high school students meet difficulties in visualizing the motion of an object in different frame of reference and in understanding how observations made by different observers are related. This paper presents a package, based on computer simulations, designed to emphasize that, to describe a motion, the observer must define a frame of reference relative to which the motion is analyzed. The package helps students to arrive by themselves to the Galilean transformation.
