Which of the following correctly shows the SI unit for the moment of inertia?
Which of the following formulas correctly relates the moment of inertia of an object, , to the mass of the object, , and the distance of the object from the axis around which it rotates, ?
A thin hoop has a radius of 1.25 m and a mass of 750 g. The hoop can rotate around an axis that intersects the hoop at the points A and B, as shown by the blue arrow in the diagram. The hoop can also rotate around an axis that intersects the midpoint of the line from A to B and does not intersect the hoop, as shown by the orange arrow. What is the difference in the moment of inertia of the hoop around these two axes?
