**Moment of Inertia Reference Frames**

The use of the inertia matrix in Newton's second law assumes its components are computed relative to axes parallel to the inertial frame and not relative to a body-fixed reference frame. This means that as the body moves the components of the inertia matrix change with time. In contrast, the components of the inertia matrix measured in a body-fixed frame are constant.

### Famous quotes containing the words moment of, frames, reference, moment and/or inertia:

“[Film noir] experiences periodic rebirth and rediscovery. Whenever we have any *moment of* deep societal rift or disruption in America, one of the ways we can express it is through the ideas and behavior in film noir.”

—John Briley (b. 1925)

“For laughter *frames* the lips of death—

Death *frames* the Singer and the Song.”

—Allen Tate (1899–1979)

“If we define a sign as an exact *reference*, it must include symbol because a symbol is an exact *reference* too. The difference seems to be that a sign is an exact *reference* to something definite and a symbol an exact *reference* to something indefinite.”

—William York Tindall (1903–1981)

“The universe seems to me infinitely strange and foreign. At such a *moment* I gaze upon it with a mixture of anguish and euphoria; separate from the universe, as though placed at a certain distance outside it; I look and I see pictures, creatures that move in a kind of timeless time and spaceless space, emitting sounds that are a kind of language I no longer understand or ever register.”

—Eugène Ionesco (b. 1912)

“What is wrong with priests and popes is that instead of being apostles and saints, they are nothing but empirics who say “I know” instead of “I am learning,” and pray for credulity and *inertia* as wise men pray for scepticism and activity.”

—George Bernard Shaw (1856–1950)
