| Abstract: | It is a demonstrative experiment about law of motion of the centroid,a group of similar rigid bodies make plane-parallel motion on the same inclined plane,and analysis it on theory.The rigid bodies having a certain symmetry distribution and density distribution have a same centroid acceleration when they make pure rolling on the same inclined plane,so the theory conforms to the experiment exactly. |

| Keywords: | rigid body similar figures surface density |
