Why is the moment of inertia of a solid sphere lower than the moment of inertia of a thin spherical shell that has the same radiusr and mass m? * Though the mass for the shell is more distributed the farther it is from the center, m*r is bigger for the shell;s case. The mass is more concentrated near the center for the shell compared to the solid's. O The mass for a sphere is less evenly-distributed than the shell's. O The mass for the shell is more distributed along the edge or far away from the center. What distinguishes an object's center of gravity (CG) to its center of mass (CM)? * The acceleration due to gravity the object is experiencing O None. CG is same as CG for rigid bodies. The object's moment of inertia
