Anno XXIX - n.4 - ottobre/dicembre 1996 Determinazione della costante di Boltzmann attraverso misure dinamiche di moti browniani
A simple check of Einstein – Smolukowskij law was performed. The observation and measurement of brownian motion is possible through a video recorder- television set. […]
Anno XLIV - n.1 - gennaio/marzo 2011 DVD in caduta
The fall of a vertical DVD upon a horizontal desk is studied. Different initial conditions are analysed with respect to the static and dynamic friction coefficients and the starting angle. Differential equations of motion are derived and numerical solutions are compared with measurements taken in simple experiments. […]
Anno XXVI - n.3 - luglio/settembre 1993 Equilibrio termico: un’esperienza introduttiva a un percorso didattico.
This paper describes an introductory experiment, leading to a definition of temperature based on the use mercury thermometer. The variation in time of the thermometer readings is the starting point for the construction of a mathematical model; this model will be later adapted to more complex systems approaching thermal – […]
Anno XLIV - n.3 - luglio/settembre 2011 Esperimenti a “costo zero” sul moto uniforme
It is possible to study the uniform motion by using common objects taken from daily life. Cans, balloons, test tubes, olive oil and glycerine allow to make self-made devices, which are easy to handle and to use. The choice of using common materials let all students reproduce the most of this equipment at home and carry out the experiments by themselves. […]
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 XLIII - n.2 - aprile/giugno 2010 Giochi ed esperimenti con le bottiglie di plastica
Some simple low cost demonstrations using plastic bottles of mineral water are reported. The experiments explore the pressure and weight of gases, Archimede’s law, gases dissolved in water, the Cartesian diver and other phenomena. […]
Anno XXVIII - n.3 - luglio/settembre 1995 Gli anelli di Newton – allora e oggi
Working in the open air Newton measured the rings and from these measurements he calculated the “fit length” of light. The author repeated Newton’s measurements. Then when he went indoors using fluorescent light he was greatly surprised at what he saw. […]
Anno XLVIII - n.1 - gennaio/marzo 2015 I crateri formati dalle meteoriti
A brief analysis of meteorites and their effects on earth is given. In particular, the paper focuses on the relationship between the energy of a meteorite fallen on the earth and the width of the crater. The reader will find a very simple experiment that simulates the fall of a meteorite and allows to measure energy and the diameter of the crater. […]
Anno LVI - n.3 - luglio/settembre 2023 Il Laboratorio di Fisica come esercitazione a casa
Integrating laboratory activities into the teaching of Physics is crucial. However, educators have long struggled with effectively leveraging laboratory resources, often constrained by the limited physics curriculum time allocated in secondary school courses. A promising solution may lie in harnessing educational technologies such as Tracker, […]
