This article deals with the very familiar phenomena in which vapour condenses, clouds are formed and, finally, it rains. It explains how this happens and why surface shape and not only temperature plays an important role in the process. […]
The author, teacher of physics at I.T.I.S. “A. Volta” (high school) of Naples, scholar of Cognitive Science, has applied the strategies of problem solving to physics. This approach gives the students the opportunity to work in an organized and productive way. […]
This experiment consists in the measurement of the oscillation period of a rigid pendulum by using the accelerometer of a smartphone and an ultrasound motion sensor […]
This article presents a simple experiment on the conduction of heat in a metallic bar. Temperatures vs time are measured on-line and plotted in real time with a PC. We discuss me data, then we evaluate heat losses along the sides of the bar and we calculate the heat transmission coefficient using a finite difference algorithm. […]
