Question

DEFINATION OF MOMENT OF INERTIA..

Answer 1

here is your answer

The moment of inertia, otherwise known as the angular mass or rotational inertia, of a rigid body is a tensor that determines the torque needed for a desired angular acceleration about a rotational axis; similar to how mass determines the force needed for a desired acceleration


Moment of inertia ( ), also called "angular mass" (kg. · m2), is the inertia of a rotating body with respect to its rotation. It is a rotating body's resistance to angular acceleration or deceleration, equal to the product of the mass and the square of its perpendicular distance from the axis of rotation.

hope you understand

Answer 2

Answer:-

• Moment of Inertia. The moment of inertia is sometimes called and referred to as "angular mass." It is the "amount of resistance" to rotational motion. ... The moment of inertia is commonly used to calculate torque when multiplied by the angular acceleration.
• Moment of inertia about a given axis of rotation resists a change in its rotational motion; it can be regarded as a measure of rotational inertia of the body.
• The formula for moment of inertia is the “sum of the product of mass” of each particle with the “square of its distance from the axis of the rotation”. The formula of Moment of Inertia is expressed as I = Σ MiRi²
