Between physical and geometric considerations: a study about the astronomical hypotheses in the first part of the work Astronomia Nova by Johannes Kepler

This article aims to present a study of some geometrical and physical aspects in the first part of the work Astronomia Nova of 1609, in order to provide subsidies to teachers who want to address the history of astronomy in their basic or higher education subjects. With this focus, we will see how Kepler understood some equivalences between the world systems under discussion in his time and present a study of one of the experiments that Kepler proposed and analyzed geometrically. In this, we noticed a small miscalculation that was not explored in the researched literature, and more than that, it allowed us to understand about the use of geometric constructions in his time and the idea of equivalence that Kepler has in mind.
