Match the term "center of gravity" with the correct description.

The term "center of gravity" refers to the point in a body where the total weight is concentrated, and it is critical for understanding how a ship behaves in water. The correct description indicates that the center of gravity will be raised if weight is added high in the ship because this concept relates directly to the ship's stability.

When additional weight is placed higher on the ship, it raises the center of gravity, which can adversely affect stability. A higher center of gravity makes the ship more likely to roll over or be affected by external forces like wind and waves. Understanding this concept is essential for effective ship management and ensuring safety at sea.

Other descriptions do not accurately encapsulate the behavior of the center of gravity as it relates to weight distribution. For instance, while the center of gravity's position can indeed move in an arc as the ship rolls, that description pertains more to the dynamics of motion rather than its response to added weight. Similarly, the statement about the center of mass could reflect inertia but does not convey the effect of weight distribution on stability as specifically as the correct choice. Lastly, the idea that the center of gravity remains constant overlooks the influence of weight changes, which is key to understanding ship stability.
