Ⅰ. Introduction
We can see lots of objects rotating - even an Earth where we live in. It is important to analyze rotational motion and, at the previous experiment we have searched of fundamentals of rotational motion and found some analogous factors between linear motion and rotational motion. The concept of momentum or conservation law can be also be extended to rotational. Momentum of linear motion is defined as the mass of an object multiplied by its velocity, however, it is difficult to explain rotational motion because its velocity varies according to many factors. For this reason, we analyzed the motion by choosing one point of the rotating object, which is called
center of mass. Generalizing the object by idealized point, we determined if the angular momentum or kinetic energy of rotating objects is also conserved.

Ⅱ. Theoretical Basis

Angular Velocity
We define the average angular velocity of the body in the time interval as the ratio of the angular displacement to :
