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 radius measured perpendicularly to the axis of rotation.
A: Moment of inertia is the inertia of a rotating body with respect to its rotation.
A: Another name for moment of inertia is "angular mass".
A: The unit of measurement for moment of inertia is kg·m2.
A: Moment of inertia represents a rotating body's resistance to angular acceleration or deceleration.
A: The equation for calculating moment of inertia is I = mr^2, where m is the mass of the rotating body and r is the radius measured perpendicularly to the axis of rotation.
A: The mass of the rotating body affects moment of inertia directly, as it is a part of the equation for calculating moment of inertia.
A: The radius of the rotating body affects moment of inertia indirectly, as it is multiplied by the square of its value in the equation for calculating moment of inertia.
