Deriving moment of inertia for sphere
WebRotational inertia is also commonly known as moment of inertia. It is also sometimes called the second moment of mass ; the 'second' here refers to the fact that it depends on the length of the moment arm squared . WebThe parallel axis theorem states that if the body is made to rotate instead about a new axis z′, which is parallel to the first axis and displaced from it by a distance d, then the moment of inertia I with respect to the new axis is related to Icm by Explicitly, d is the perpendicular distance between the axes z and z′ .
