Final answer:
The center of gravity is the balance point of an object where the total weight is assumed to be concentrated. It contributes to rotational inertia and angular momentum.
Step-by-step explanation:
The center of gravity refers to the point where the total weight of an object is assumed to be concentrated. It is the balance point of an object, and it contributes to the object's rotational inertia and angular momentum. The center of gravity is identical to the center of mass for most practical situations, as long as the gravitational field is uniform throughout the object's volume. It is important to note that the center of gravity can be affected if an object has a nonuniform distribution of weight.
