[size=150]The aim of this presentation is to show the use of GeoGebra to illustrate the base idea of geometric proof of the 1[sup]st[/sup] (law of ellipses) and 2[sup]nd[/sup] (law of equal areas) Kepler’s laws by Richard Feynman.[br][br]My earlier work on the same topic, dealing with the numerical model will also be mentioned.[/size][br][br][size=150][b]GeoGebra provides an environment suitable for the realization of both numerical and geometric models of planetary motion.[/b][/size]
