moment of inertia

n. pl. moments of inertia
A measure of a body's resistance to angular acceleration, equal to:
a. The product of the mass of a particle and the square of its distance from an axis of rotation.
b. The sum of the products of each mass element of a body multiplied by the square of its distance from an axis.
c. The sum of the products of each element of an area multiplied by the square of its distance from a coplanar axis.
