Anno XXV - n.4 - ottobre/dicembre 1992 Flusso laminare di un fluido intorno ad un corpo sferico. (Traduzione da School Science Review, vol. 71, n. 257,a cura di Silvia Pugliese Jona)
A simple experiment to demonstrate streamline flow around a sphere falling at terminal velocity in a viscous fluid. […]
Anno XXXVII - n.2 - aprile/giugno 2004 Fontanella fotovoltaica
A ‘photovoltaic fountain’ uses solar energy to drive a water pump. The nature of the energy source is made evident by the immediate response of the height of the water jet to changes in the intensity of the sunlight. […]
Anno XLII - n.4 - ottobre/dicembre 2009 Force Concept Inventory: un questionario per valutare l’efficacia dell’insegnamento della dinamica
The Force Concept Inventory is designed to evaluate the teaching quality of a course on Newtonian mechanics. The structure of the FCI and its reference to students’ common concepts and misconceptions are discussed in relation to some of its items. Two actual examples of how the results can be analyzed are presented. […]
Anno XXV - n.2 - aprile/giugno 1992 Formazione degli insegnanti nella Repubblica Federale Tedesca
This article discusses the education of school-teachers in Western Germany alter the sixties, in the context of the school System, and reports the curriculum adopted in 1987 at the University of Kiel for students preparing to become physics teachers. […]
Anno LIV – n.2 – aprile/giugno 2021 Forze di marea, navicelle spaziali e principio di equivalenza
As it is written in many books, within a vehicle in free fall or in a spacecraft orbiting the Earth, everything goes as if there were no gravity, a situation commonly described as “weightlessness.” In the handbooks on relativity, a free-falling vehicle is considered as an example and a practical realization of an inertial reference system. […]
Anno XXVIII - n.1 - gennaio/marzo 1995 Forze elettrodinamiche in corrente alternata
Several demonstrations are described, illustrating dynamic interactions between alternating currents and fields. […]
Anno XL - n.4 - ottobre/dicembre 2007 Galleggianti che si attraggono
We can commonly notice small things – leaves, pieces of paper, etc., – adhering to each other and floating together on the water. The reasons of this behaviour are explained. […]
