| Abstract: | In order to deepen the study on the hockey, it is necessary to measure some physical propertics for hockey. These physical propertics include the mass, the centre of gravity, the moment of inertia and the centre of percussion of a club. And also it includes the mass and diameter of a ball, and the coefficient of restitution between a ball and a club. In this paper, these propertics are measured experimentally, and the results are yielded. It furnishes a quantitative basis for deepening the study on the hockey later. Moreover, it gives a revised formula suited to practice in treating the experimental data. |
