Motion Analysis of a Rocking Wooden Toy with a Glass Ball Going Down a Slope

Abstract

In this study, we developed rocking wooden toys as teaching materials in early childhood education and analyze their motion through experiments and simulations. The toys have a glass ball inserted in the bottom hole of the body, and the hole is covered with an annular cork sheet. They convert potential energy into kinetic energy and move with rotation and rolling on a slope. In this study, we experimented by changing the height of the toys and clarified the change in motion and the operating principle by simulation analysis.
