Anno XXIV - n.3 - luglio/settembre 1991 The exercise described in this article incorporates several features noteworthy of a physics problem and may serve as a model for creating other exercises. A wooden rod is free to rotate in a vertical plane around its upper end, with its lower end dipping into water. […]
Anno XLVIII - n.4 - ottobre/dicembre 2015 This article reports about some experiments on the physics of resonance and elasticity. Employing a simple setup it is possible to identify the longitudinal eigenmodes of a stretched massive spring and to study their behaviour under the conditions of forced and damped motion. […]
Anno XLV - n.1 - gennaio/marzo 2012 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 This article analyses the rigid body motion in presence of friction […]
Anno XXIII - n.4 - ottobre/dicembre 1990 Measuring the brownian motion of latex microspheres leads to an evaluation of Avogadro’s number. […]
Anno XLII - n.4 - ottobre/dicembre 2009 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 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 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 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. […]
