Spazi diversi in tempi uguali lungo le corde di una circonferenza

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. We refer to the experiment carried out by the scientific association ScienzaViva at the show “Tribute to Galileo 450 years after his birth”.
