The centroid, or center of gravity, of any object is the point within that object from which the force of gravity appears to act. • An object will remain at rest if it is balanced on any point along a vertical line passing through its center of gravity.
Moment of Inertia - It is a measure of an object’s resistance to changes to its rotation. Also defined as the capacity of a cross-section to resist bending. . It must be specified with respect to a chosen axis of rotation. • It is usually quantified in m4 or kgm2.
