Articoli rivista
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 XXVIII - n.3 - luglio/settembre 1995 Moti composti in presenza di attrito
This article analyses the rigid body motion in presence of friction […]
Anno XXIII - n.4 - ottobre/dicembre 1990 Moto browniano: esperimento di laboratorio. (Traduzione da Physics Education 23 (1988), a cura di Matilde Cilento)
Measuring the brownian motion of latex microspheres leads to an evaluation of Avogadro’s number. […]
Anno XLII - n.4 - ottobre/dicembre 2009 Moto delle cariche in un campo magnetico non uniforme
The trajectories of charged particles in the non-uniform magnetic field generated by two parallel identical currents are studied. Although this case is not usually considered in the high school, its basic aspects are not too difficult and can be understood by the students. […]
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. […]
