🔍 Key Concepts

• The six degrees of freedom of ship motion (three linear, three rotational) • Difference between longitudinal (fore‑and‑aft), vertical, and transverse (sideways) motion • How transverse/lateral stability is defined in naval architecture

💭 Think About

• Identify which listed motions are straight‑line (translational) motions versus rotational motions around the ship’s axes • Ask yourself: when we talk about a vessel’s ability to resist rolling over sideways, which basic direction of movement is most directly related to that sideways, transverse behavior? • Match the word lateral (sideways) with the correct axis and motion among the six degrees of freedom.

✅ Before You Answer

• Be clear which axis is fore‑and‑aft, which is athwartships (side to side), and which is vertical • Verify which motion term describes side‑to‑side straight‑line movement of the ship’s center of gravity, not rotation • Confirm that the motion you pick is the one most closely tied to transverse (lateral) stability in basic ship stability theory.
