An important aspect of school Physics is to show how different phenomena can be set in the framework of the same general law. In this context I propose a unified treatment of the properties of lenses and mirrors based on the concept of ideal optical system and on the thin lens (and spherical mirror) approximation that describe in a general manner the behaviour of such devices.

The conditions why objects rolling down different inclined tracks cover different distances in equal interval of time are studied. We want to demonstrate that the time taken by a ball to cover a chord of a circumference because of gravity, does not depend on the length of the chord itself. […]
