Web7.4.1 Intro to Mass Moment of Inertia. Mass moment of inertia, or inertia as it will be referred to from here on, is resistance to rotation. The bigger the inertia, the slower the rotation. ∑M = I α ∑ M = I α. Inertia is always positive and has units of kgm 2 or slugft 2. For an infinitesimal unit of mass, the inertia depends on how far ... WebInertia is the property of matter which resists change in its state of motion. Inertia is a measure of the force that keeps a stationary object stationary, or a moving object moving at its current speed. The larger the inertia, the …
