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