Anno XXIX - n.3 - luglio/settembre 1996 Un sistema a fotocellule per esperienze di meccanica
This note describes a system based on photogates and interfaced to a PC that can be particularly useful in physics experiments in which the description of objects’ motion is relevant. The PC role is twofold: on one side it is the system timer, […]
Anno XXXI - n.3 - luglio/settembre 1998 Una bambola che cambia colore
A simple to make but not so simple to explain experiment on polarized light is described and explained. […]
Anno XLVI - n.2 - aprile/giugno 2013 Una caccia al tesoro scientifica: dove sta l’accelerometro in uno smartphone?
Current smartphones are equipped with many sensors and that offer a wide choice of applications like measuring accelerations, sounds, distances, angles, etc. Smartphones are becoming increasingly widespread among students who could use them as “personal instruments” for physics measurements. The article describes a kind of scientific treasure hunt: finding the location of the smartphone’s accelerometers by applying the laws of physics of uniform circular motion […]
Anno XXXIX - n.2 - aprile/giugno 2006 Una descrizione fisica del volo
Why airplanes have lift is commonly explained with reference to the Bernoulli principle. This simplistic ‘explanation’ is wrong and cannot account for a number of important features of flying. The physics of flight entails an understanding of Newton’s laws of dynamics and of the viscous properties of air. […]
