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. […]
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. […]
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. […]
This article analyses the rigid body motion in presence of friction […]
Measuring the brownian motion of latex microspheres leads to an evaluation of Avogadro’s number. […]
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. […]
This article shows how to make equipment for studying the performance of a water rocket, e.g. its acceleration versus air pressure and mass. […]
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? […]
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. […]
