Because it is a measure of the "resistence" of an object to be accelerated in its rotation. An object with a big moment of inertia is more difficult to increase/decrease its angular velocity (speed of rotation), than an object with a low moment of inertia.
Law of inertia.
newton's first law of motion is also known as LAW OF INERTIA. inertia is the property of a body by which every body if is in rest it tends to remain in rest and if in motion it tends to remain in motion.
Anything with mass will resist acceleration. So says Newton, and he's right.
how is the object affected by newton's 1st law? HorseIsle Answer: Inertia

Moment of inertia and rotational inertia are essentially the same concept, referring to an object's resistance to changes in its rotational motion. Moment of inertia is the term commonly used in physics, while rotational inertia is a more general term that can also be used. In the context of rotational motion, both terms describe how the mass distribution of an object affects its ability to rotate. The moment of inertia or rotational inertia of an object depends on its mass and how that mass is distributed around its axis of rotation. In summary, moment of inertia and rotational inertia are interchangeable terms that describe the same physical property of an object in rotational motion.
Rotational inertia is sometimes called spin. It involves the movement of a mass around an axis. This moving mass will have some measure of kinetic energy that is due to the fact that it is spinning. The variables are the shape and the mass of the object, the way the mass is distributed within the object, the speed of its rotation, and the location of the axis of spin through the object. The moment of inertia might also be called angular mass, mass moment of inertia, rotational inertia, or polar moment of inertia of mass. Use the link below for more information.
Moment of inertia is a measure of an object's resistance to changes in its rotational motion, based on its mass distribution. Moment of force, also known as torque, is a measure of the rotational force applied to an object to produce rotational motion. In essence, moment of inertia describes an object's inherent property, while moment of force describes an external force acting on an object.
YES. Infact, an object can have infinitely different moment of inertias. It all depends on the axis about which it it rotating. You can allow an object to rotate about any axis (this may or may not pass through the object).
Increasing the mass of an object will increase its inertia. Also, increasing the speed at which an object is spinning will increase its rotational inertia. Additionally, increasing the distance of an object from the axis of rotation will increase its rotational inertia.
The moment of inertia depends not only on the mass of an object but also its shape and distribution of mass. Objects with different shapes will have different moments of inertia even if they have the same mass. Therefore, the moment of inertia is not necessarily constant for a constant mass.
Rotational inertia is directly proportional to the mass of an object and to the square of its distance from the axis of rotation. If the size of an object changes but the mass remains the same, the rotational inertia will also change because the distribution of mass relative to the axis of rotation will change.
The momentum of inertia, also known as rotational inertia, is a measure of an object's resistance to changes in its rotational motion. It depends on the mass and distribution of mass of an object relative to its axis of rotation. A larger momentum of inertia makes it harder to accelerate or decelerate the object's rotation.
Polar moment of inertia of an area is a quantity used to predict an object's ability to resist torsion.Moment of inertia, also called mass moment of inertia or the angular mass, (SI units kg m2, Imperial Unit slug ft2) is a measure of an object's resistance to changes in its rotation rate.
Sources of error in the experiment of moment of inertia of a solid cylinder can include friction in the rotating system, inaccuracies in the measuring instruments such as rulers or calipers, variations in the dimensions of the cylinder, and errors in the calculation of the rotational inertia formula. Additionally, external factors like air resistance or vibrations can also introduce errors in the experiment.
Rotational inertia depends on the mass of the object and how that mass is distributed around the axis of rotation. It is also influenced by the shape and size of the object.
Just moment of inertia is incomplete requirement as the axis about which it is to be measured is also very important
