If the moment of inertia of a body changes due to a change of axis of rotation, the new moment of inertia can be calculated using the parallel axis theorem. This theorem states that the moment of inertia about a new axis parallel to the original axis can be found by adding the mass of the body multiplied by the square of the distance between the two axes.

What is the moment of inertia about an axis of rotation body?
The moment of inertia of a body about an axis of rotation is a measure of its resistance to rotational motion. It depends on the mass of the body and how that mass is distributed around the axis of rotation. A body with a larger moment of inertia requires more torque to rotate at the same rate as a body with a smaller moment of inertia.
How do you calculate the moment of inertia for a given object?
To calculate the moment of inertia for a given object, you need to know the mass of the object and the distance of each particle from the axis of rotation. The moment of inertia is calculated by summing the mass of each particle multiplied by the square of its distance from the axis of rotation. This calculation helps determine how difficult it is to change the object's rotational motion.
How to find the moment of inertia for a given object?
To find the moment of inertia for a given object, you need to know the mass of the object and the distance of each mass element from the axis of rotation. The moment of inertia is calculated by summing the products of each mass element and its distance squared from the axis of rotation. The formula for moment of inertia varies depending on the shape of the object.
What is the moment of inertia of a rod with a mass attached at one end?
The moment of inertia of a rod with a mass attached at one end is calculated using the formula for a point mass at a distance from the axis of rotation. The moment of inertia of the rod itself is also considered in the calculation. The final moment of inertia depends on the mass of the rod, the mass attached at one end, and the distance of the mass from the axis of rotation.
Why is moment of inertia of a solid disc smaller than that of a ring?
Moment of inertia depends upon the distribution of mass with respect to the axis of rotation.The greater the distance between the bulk of an object's mass and the axis of rotation, the greater the moment of inertia will be. A solid disk has its mass distributed evenly across its diameter, while a ring has its mass concentrated furthest from the centre of rotation.

Why is it necessary to mention the axis of rectangular bar while calculating the moment of inertia?
An object rotating about its long axis will have a different moment of inertia than when it is rotating about its short axis. A solid disk will have a different moment than a washer, and there are formulas derived for calculating the moments of many common shapes.

A solid disk has its mass distributed evenly across its diameter, while a ring has its mass concentrated furthest from the centre of rotation.
Why does the solid disk have a greater moment of inertia than the solid sphere, and how can this difference be explained?
The solid disk has a greater moment of inertia than the solid sphere because the mass of the disk is distributed farther from the axis of rotation, resulting in a larger rotational inertia. This difference can be explained by the parallel axis theorem, which states that the moment of inertia of an object can be calculated by adding the moment of inertia of the object's center of mass and the product of the mass and the square of the distance between the center of mass and the axis of rotation.
What is the moment of inertia of a cylinder?
(1/2) mr2, assuming the axis of rotation goes through the center, and along the axis of symmetry.
What is moment of inertia and how does it effect on angular speed?
Moment of Inertia is defined as the product of mass and square of distance from its axis of rotation and it is denoted by I. I=mR2 Moment of Inertia depends upon mass from the axis of rotation of wheel rim e.g because the mass of big bicycle lie away from the axis of rotation of wheel rim.So M.O.I of big bicycle is Small than small Bicycle.
How can one determine the moment of inertia of an object?
To determine the moment of inertia of an object, you need to know the mass of the object and how the mass is distributed around its axis of rotation. The moment of inertia is calculated using the formula I miri2, where mi is the mass of each small part of the object and ri is the distance of that part from the axis of rotation. By summing up the contributions of all the small parts, you can find the total moment of inertia of the object.
What is the moment of inertia of a rod with a mass attached to it?
The moment of inertia of a rod with a mass attached to it is a measure of how difficult it is to change the rod's rotational motion. It depends on the mass of the rod and the mass of the attached object, as well as the distance between them and the axis of rotation.
What is the moment of inertia for discrete system?
The moment of inertia for a discrete system is the sum of the products of the mass of each particle and the square of its distance from the axis of rotation. It quantifies an object's resistance to changes in its rotation. It is calculated using the formula I = Σmiri^2, where mi is the mass of each particle and ri is its distance from the axis of rotation.
