Moment of Inertia | Engineering Mechanics | NCERT PHYSICS | IIT-JEE
The moment of inertia of an object is a calculated measure for a rigid body that is undergoing rotational motion around a fixed axis: that is to say, it measures how difficult it would be to change an object's current rotational speed. That measurement is calculated based upon the distribution of mass within the object and the position of the axis, meaning that the same object can have very different moment of inertia values depending upon the location and orientation of the axis of rotation.
Using Moment of Inertia
The moment of inertia of an object rotating around a fixed object is useful in calculating two key quantities in rotational motion:
Rotational kinetic energy: K = Iω2
Angular Momentum: L = Iω
You may notice that the above equations are extremely similar to the formulas for linear kinetic energy and momentum, with moment of inertia "I" taking the place of mass "m" and angular velocity "ω" taking the place of velocity "v," which again demonstrates the similarities between the various concepts in rotational motion and in the more traditional linear motion cases

Glad to help. Can we know your stream? Helps us to customize to your needs.
the value of the moment of inertia is used to calculate how much power does it requires to rotate a wheel from idle to n rpm all the physics students are trying to understand it. and no one had given exact explanation. this is more like pi of the circle
Thank you for the explanation, it was very quick and simple to understand :)
