Anno XLI - n.1 - gennaio/marzo 2008 Misura del momento d’inerzia di un libro
The relationship between the moment of inertia of a body and its period of twisting oscillation was studied in the classroom by suspending a book, in three different orientations according to its symmetry axes, to the edge of a table with a length of tape. […]
Anno XXVI - n.2 - aprile/giugno 1993 Misura dell’accelerazione di gravità con un semplice dispositivo on-line
This paper describes a measurement of the acceleration due to gravity done using a simple device connected to a computer on line. […]
Anno XXVII - n.1 - gennaio/marzo 1994 Misura della circonferenza terrestre col metodo di Eratostene.
This article describes an experiment done by first-year secondary school pupils, who measured me radius of the Earth with the method of Erathosthenes. For this purpose, cooperation was sought for and put into effect on long European distances, ranging from the island of Pantelleria in the Mediterranean to Goteborg in Sweden. […]
Anno XLVII - n.2 - aprile/giugno 2014 Misura della componente orizzontale del campo magnetico terrestre mediante una bilancia elettromagnetica costruita in casa
We report an experiment for measuring the horizontal component of the Earth’s magnetic field using easily available material, explaining how some conditions that optimize the results were obtained using a rectangular coil. […]
Anno XXXI - n.3 - luglio/settembre 1998 Misura della costante h/e (costante di Planck/carica elementare) mediante diodi L.E.D.
By means of some LEDs (Light Emitting Diodes) used as quasi-monochromatic light sources at different wavelengths and measuring their forward voltage at a fixed value of the current one can obtain the ratio of Planck’s constant to elementary charge with an estimated error of the order of 6%. […]
Anno XXVIII - n.3 - luglio/settembre 1995 Misura della lunghezza d’onda della luce con un disco microsolco
This article describes how it is possible to measure the light wavelength using a phonograph microgroove disc. […]
Anno XLVII - n.3 - luglio/settembre 2014 Misura della velocità della luce con mezzi modici
A simple way of measuring the speed of light in an educational context using one or a couple of mirrors and some easily available common electronic equipment is described. […]
Anno XXXVI - n.3 - luglio/settembre 2003 Misurare la velocità tramite l’effetto Doppler
Velocities are measured through the interference of waves of slightly different frequencies due to the Doppler effect. The experiment is performed with mechanical (ultrasound) and electromagnetic (laser light) waves. The ultrasound results are compared with velocities measured in an independent way. […]
Anno XLVIII - n.3 - luglio/settembre 2015 Misurare pi-greco
This article describes an activity aimed at measuring the value of pi. Five methods, were used, all of them easy to perform. All results agree with the known value within 1%. The activity is suitable to introduce the concept of measurement uncertainty at the beginning of Physics Classes. […]
