Anno XLV - n.1 - gennaio/marzo 2012 Molle in serie e in parallelo
Hooke’s Law applied to a number of springs connected in series (same strength) or in parallel (same elongation) suggests a mechanical analogy to the electrostatic behavior of a number of series or parallel connected capacitors. […]
Anno XLV - n.2 - aprile/giugno 2012 Moto di un razzo ad acqua
This article shows how to make equipment for studying the performance of a water rocket, e.g. its acceleration versus air pressure and mass. […]
Anno XXXII - n.4 - ottobre/dicembre 1999 Moto di una bolla d’aria in un tubo d’acqua
An experiment made by some students of the “Liceo Scientifico” about the motion of an air bubble in a tube filled with water. What is the inclination of the tube for the highest speed of the bubble? […]
Anno XXX - n.2 - aprile/giugno 1997 Moto di una goccia d’acqua in olio d’oliva
The falling motion of a drop of distilled water inside a transparent graduated cylinder containing domestic olive oil was studied. The results of the measurements taken were worked out so that a direct proportionality between the velocity of the drop and the area of its maximum cross section could be verified. […]
Anno XXIX - n.3 - luglio/settembre 1996 Movimento degli ioni in soluzione salina
This article the presents the results of a research on the change of electric voltage across a voltmeter, during the solution of a wheat of salt. It could be a stimulus for subsequent developments, even involving the class and the chemistry teacher in the project area of the biennium of the technical industrial institutes. […]
Anno XLVIII - n.4 - ottobre/dicembre 2015 Nuove tecniche di analisi dei moti
This article describes a new method for studying motion, with characteristics similar to those of photo strobes. This uses a mobile phone, some free PC programs and a printer and can therefore be used in the absence of a true laboratory. […]
Anno XXXI - n.1 - gennaio/marzo 1998 Pendolo di Foucault in miniatura da esposizione
A 3.5-meter long Foucault pendulum is realized for teaching and exhibition purposes. The pendulum operates continuously without need for maintenance or external control. The decay of the oscillation amplitude due to friction is compensated by the application of a pulsed central magnetic force, […]
Anno XXVI - n.1 - gennaio/marzo 1993 Polarizzazione della luce e legge di Malus
This article describes an experiment on Malus’ Law for polarized light, using a LED as light source, two polaroid sheets as polarizers and a phototransistor as receiver. […]
Anno XXXI - n.4 - ottobre/dicembre 1998 Quantizzazione della conduttanza in contatti d’oro unidimensionali
Using a very easy experiment, conductivity quantization can be observed. In this way quantum mechanics becomes something students can also experiment. […]
Anno XLIII - n.4 - ottobre/dicembre 2010 Riga da disegno usata come bilancia a pendolo
An experimental exercise on using a pendulum for measuring masses, proposed to the Italian students enrolled in one of the national sessions of the Physics Olympiads, is described and discussed. […]
