10.6 Exercise 6

Why is it important to consider the shape of an object when determining the object's angular momentum?

1. The shape determines the location of the center of mass. The location of the center of mass in turn determines the angular velocity of the object.
2. The shape helps you determine the location of the object's outer edge, where rotational velocity will be greatest.
3. The shape helps you determine the location of the center of rotation.
4. The shape determines the location of the center of mass. The location of the center of mass contributes to the object's rotational inertia, which contributes to its angular momentum.
