スマートフォンを用いた物理実験

（授業との連携）

抄録

Smartphones have become an everyday necessity. Experiments that utilize their convenience and functions can help students to better understand physics. In this report, we introduce a method to analyze the motion of a circular body rolling on a horizontal plane or an inclined plane by videotaping it with a smartphone. In particular, students can deepen their understanding of the theory of rigid body motion through actual experiments on the rotational motion of rigid bodies, which they learn in class.
