Analysis Moment of inertia, also called mass moment of inertia, rotational inertia or the angular mass,It is a measure of an object's resistance to changes to its rotation. It is the inertia of a rotating body with respect to its rotation. The disk has an experimental value of inertia of 142,869.79gcm 2 and the Ring has an experimental value of inertia of 52,743.06gcm 2 . They have different moments of inertia because one is easier to be rotated about a desired axis ( about its center), meaning the one with much smaller moment of inertia needs lesser force to rotate, because its resistance to change in its rotation is lesser Even though the Disk and the Ring almost have the same mass, the Disk has a greater moment of inertia because it produces greater Torque which means from the formula of torque T = r x F where r is the radius or the length of its lever arm, where the radius of the disk is acting as its lever arm while the disk is being rotated about its center. And for the Ring, it has hollow shaped body, means that the we need to compute first the difference of the radius from the outer ring to the inner ring therefore making the lever arm more smaller thus easier for it to rotate therefore lesser moment of inertia\
