Abstract

This paper outlines a deceptively complex problem in classical mechanics which the paper names the "Falling Astronaut Problem," and it explores a method for teachers to implement this problem in an undergraduate classroom. The paper presents both an analytical solution and a numerical approximation to the Falling Astronaut Problem and compares the educational merit of the two approaches. The analytical solution is exact; however, the derivation requires techniques that are more advanced than what is typically seen in an introductory undergraduate physics course. In contrast, the numerical approximation presents a novel application of concepts with which a first-semester undergraduate is likely to be familiar. The paper stresses the pedagogical implications of this problem, specifically the opportunity for introductory undergraduate students to learn the utility of differential equations, numerical approximations, and data spreadsheets. On a more fundamental level, the paper argues that the Falling Astronaut Problem presents an instructional opportunity for physics students to acquire a nuanced and informative lens through which to conceptualize cause and effect in the universe.
