**Moment of Inertia**

The moment of inertia of an object, symbolized by **I**, is a measure of the object's resistance to changes to its rotation. The moment of inertia is measured in kilogram metre² (kg m²). It depends on the object's mass: increasing the mass of an object increases the moment of inertia. It also depends on the distribution of the mass: distributing the mass further from the centre of rotation increases the moment of inertia by a greater degree. For a single particle of mass a distance from the axis of rotation, the moment of inertia is given by

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

“The moment one accosts a stranger or is accosted by him is above all in this life the *moment of* drama.... Whoever we meet watches us intently at the quick, strange *moment of* meeting, to see whether we are disposed to be friendly.”

—Haniel Long (1888–1956)

“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)

“I believe that in the history of art and of thought there has always been at every living *moment* of culture a “will to renewal.” This is not the prerogative of the last decade only. All history is nothing but a succession of “crises”Mof rupture, repudiation and resistance.... When there is no “crisis,” there is stagnation, petrification and death. All thought, all art is aggressive.”

—Eugène Ionesco (b. 1912)
