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 LVI - n.1 - gennaio/marzo 2023 Forze, inerzia e moto da Aristotele alla didattica dei giorni nostri
In this work, we will examine the historical evolution of the core of dynamics, the relationship between forces and motion, focusing particularly on the principle of inertia. Our aim is to highlight an aspect that seems to us to be largely underestimated in literature, […]
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. […]
Anno XXIV - n.2 - aprile/giugno 1991 Gas perfetti e gas reali. 1° Premio: Liceo Scientifico Statale “A. Tassorlin, Modena
We begin to study the properties of gases through a well-known mechanical model, then we perform a school-Iab replica of Volta’s experiment on the dilatation of gases at constant pressure. After observing that the behaviour of air is close to that of ideal gases, […]
Anno XXIV - n.2 - aprile/giugno 1991 Gas perfetti e gas reali. 2° Premio: Liceo Classico “Virgilio”, Empoli FI
A few experiments on the behaviour of real gases were performed. They show that the behaviour of air at constant temperature is quite similar to that of an ideai gas but, at constant pressure and varying temperature, the different behaviours of various gases (air, […]
