ABSTRACT

Is the reluctance of an object or body to start rotating or change its state of rotation (i.e., speed up or slow down). It is measured as the product of the mass of the body and the distance of the mass from the axis of rotation squared (I = mr2). Double the axis of rotation of the mass and you will quadruple the moment of inertia value. The moment of inertia value can be changed by redistributing the body mass about the axis of rotation (such as in the case of “tucking” or extending the body during a somersault).
