... of particles is given by Use the center of mass C as the reference point so and define the moment of inertia relative to the center of mass IC as then the equation for angular momentum simplifies to ... For a given amount of angular momentum, a decrease in the moment of inertia results in an increase in the angular velocity ... Figure skaters can change their moment of inertia by pulling in their arms ...
Inertia Tensor
... In classical mechanics, moment of inertia, also called mass moment of inertia, rotational inertia, polar moment of inertia of mass, or the angular mass (SI units kg·m2, US units lbm ft2), is a property of a ... This scalar moment of inertia becomes an element in the inertia matrix when a distribution of mass is measured around three axes in space ... This inertia matrix appears in the calculation of the angular momentum, kinetic energy and resultant torque in the dynamics of a rigid body ...
Rhea (moon) - Physical Characteristics - Size, Mass and Internal Structure
... published in 2007 it was claimed that the axial dimensionless moment of inertia coefficient was 0.4 ... some compression of ice in the center) while the existence of a rocky core would imply a moment of inertia of about 0.34 ... the same year another paper claimed the momentum of inertia was about 0.37 implying that Rhea was partially differentiated ...
Inertia Tensor - Moment of Inertia Around An Arbitrary Axis
... The moment of inertia of a body around an arbitrary axis in space is a scalar that is computed as the sum of the distance squared from the axis to ... This scalar can be computed from the moment inertia matrix of the body using the unit vector along the axis ... Choose R as a reference point and compute the moment of inertia around an axis L defined by the unit vector S through the reference point R ...

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

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)

After a moment of shrinking back, we domesticate the grotesque.
Mason Cooley (b. 1927)
