This physical quantity is unchanged in certain situations, according to the Stretch Rule.
This physical quantity is unchanged in certain situations, according to the Stretch Rule. This quantity for a uniform rod is four times as large when measured from the end instead of from the center. When measured through the center of a uniform sphere, this quantity is equal to two fifths times the (*) total mass times the radius squared. The parallel axis theorem can be useful for determining this quantity. It is equal to angular momentum over angular velocity or torque over angular acceleration. For 10 points, name this quantity equal to mass times distance squared, the rotational analog of mass.
