Factor 2 appears because of symmetry considerations as the right hemisphere has same mi as that of left one. Polar moment of inertia formula. For example, the moment of inertia can be used to calculate angular momentum, and angular energy. Rotation axis, as a quantity that decides the amount of torque required the formula for moment of inertia is the sum of the product of mass of each particle with the square of its distance from the axis of the rotation. The greater its value, the greater the moment required to provide a given acceleration about a fixed pivot. The other formulas provided are usually more useful and represent the most common situations that physicists run into.

Where, m = angular mass of the hollow material d = distance between axis and rotation. These pictures describe the moment of inertia formulas for different shapes. Theorem of the perpendicular axis. The moment of inertia is a value that measures how difficult it is to change the state of an object's rotation. In general case, finding the moment of inertia requires double integration or triple integration. Mass moment of inertia is defined as For rigid bodies with continuous distribution of adjacent particles the formula is better expressed as an integral. For a material point of mass m, which rotates around an axis at a distance r, this formula will have the following form:
