Can anybody give Some Explanation about Momemet of inertia.Kindly let me know the idea
Any help would be highly appreciated.

Moment of inertia is a measure of an object's resistance to changes in its rotational motion. It is a physical property of an object that depends on its mass distribution and the axis of rotation.
The moment of inertia of a point mass is calculated by multiplying its mass by the square of its distance from the axis of rotation. For extended objects, the moment of inertia is calculated by integrating the mass distribution over the object's volume or surface.
Moment of inertia plays a crucial role in many physical phenomena, including rotational motion, stability of objects, and conservation of angular momentum. It also has practical applications in engineering and design, such as in the construction of rotating machinery.
The moment of inertia is directly proportional to the object's mass and the square of its distance from the axis of rotation. Therefore, changing the shape of an object can significantly affect its moment of inertia. For example, a solid cylinder has a different moment of inertia than a hollow cylinder with the same mass and dimensions.
Yes, the moment of inertia can change if the object's mass distribution or axis of rotation changes. For example, if a rotating object's mass is redistributed, its moment of inertia will also change. Additionally, changing the axis of rotation will also affect the moment of inertia of an object.
