Rollinde, Emmanuel; Decamp, Nicolas; Derniaux, Catherine – Physical Review Physics Education Research, 2021
The experiment that we present in this paper explores the teaching of Galilean motion principles observed in different reference frames, in an astronomical context. All grade 10 students in a French high school (the lycĂ©e Condorcet, Val de Marne) participated in two successive teaching-learning sessions, designed within the theoretical framework…

Provost, J.-P.; Bracco, C. – European Journal of Physics, 2009
Proceeding like Newton with a discrete time approach of motion and a geometrical representation of velocity and acceleration, we obtain Kepler's laws without solving differential equations. The difficult part of Newton's work, when it calls for non-trivial properties of ellipses, is avoided by the introduction of polar coordinates. Then a simple…
