🔍 Key Concepts

• moment as a physics and stability term (force or weight × distance) • difference between a moment and a center of gravity (CG) location like TCG • how shifting a weight off the vessel’s centerline affects transverse stability

💭 Think About

• When you multiply a load’s weight by its distance from the centerline, are you calculating a position (like a CG) or an effect (like a rotational tendency)? • Which answer choices are pure locations (measured just in feet or meters) and which are products of weight × distance (measured in foot‑tons, meter‑tonnes, etc.)? • Think about what quantity is used to determine how strongly a weight tends to heel a vessel sideways: is it a CG coordinate or a moment?

✅ Before You Answer

• Identify which options represent a coordinate (just a distance from centerline) rather than a product of weight and distance. • Check which term is defined in stability as weight × transverse distance from centerline. • Confirm units: a moment will have weight × distance units, not just distance.
