🔍 Key Concepts

• Metacenter (M) vs center of gravity (G) vs center of buoyancy (B) • Definition of metacentric height (GM) • Definition of metacentric radius (BM)

💭 Think About

• Think about what two points are used to define metacentric height (GM) and what distance that represents. • Ask yourself: which term in the choices refers specifically to the distance involving the metacenter (M) and the center of buoyancy (B)? • Eliminate any option that clearly describes a point (like G, B, or M) instead of a distance between two points.

✅ Before You Answer

• Identify which quantity is the distance between G and M (that’s GM). • Identify which quantity is the distance between B and M (that’s another named distance). • Make sure the option you choose describes a distance (a length between two points), not just the location of a single point.
