Question 1 of 27070

The vertical motion of a floating vessel in which the entire hull is lifted by the force of the sea is known by which term?

🔍 Key Concepts

• Ship motions in six degrees of freedom: surge, sway, heave, roll, pitch, yaw • Which motions are up‑and‑down, which are side‑to‑side, and which are forward‑back along the vessel’s axes • How the entire hull moving vertically differs from bow/stern or side‑to‑side motions

💭 Think About

• Think about which motion describes the vessel moving straight up and down in the water without tilting forward/back or side to side • Ask yourself: which terms are associated with rotation (turning/tilting) and which are associated with translation (sliding/moving) • Match each option to its axis: along the ship’s length (fore‑and‑aft), across the ship’s beam (athwartship), or vertically (up and down)

✅ Before You Answer

• Identify which choices describe rotational motion vs straight‑line (translational) motion • Confirm which specific term is used for vertical up‑and‑down motion of the ship’s center of gravity • Eliminate any terms that clearly refer to motion forward/back along the track or sideways across the track rather than vertical motion
