| Abstract: | Moment of inertia is used to measure the intertia when rigid body rotate around the axis, which is an important conceptin mechanics. This paper, from the definition of moment of momentum and rotational kinetic energy, calculated the moment of inertia ofseveral regular shape rigid body. The process is easy for students to understand and master, and can help them in exploring the new approach to solve this kind of problems. |
