For an arbitrary object and arbitrary axes, it can be represented as a symmetric rank-two tensor.
For an arbitrary object and arbitrary axes, it can be represented as a symmetric rank-two tensor. Once known about the center of mass, it can be calculated for motion about any other point through the parallel axis theorem. The torque on an object is equal to this quantity times the angular acceleration, while the rotational kinetic energy is one half times this quantity times the angular velocity squared. For ten points, name this rotational analog of mass, which for a solid sphere is two-fifths times mass times radius squared about its center.
