🔍 Key Concepts

• Period of roll in ship stability: how long one complete oscillation of rolling motion takes • Difference between half cycle (one side to the other) and full cycle (back to the same condition) of motion • How a pendulum’s swing is timed as an analogy for a vessel’s roll

💭 Think About

• If you watch the vessel’s deck edge in a seaway, what two repeating positions would you time between to get one full cycle of roll? • Think about a child’s swing: what points in the motion define one complete swing versus just a half swing? • Which options describe a position that is exactly repeated, showing the motion has returned to its starting condition?

✅ Before You Answer

• Identify which options describe a repeating position (start and finish look the same) rather than two different positions • Decide whether a complete period of roll should include motion to both sides or just to one side and back • Check which answer corresponds to one full oscillation, not just passing through level (zero) or going from one extreme to the opposite extreme only
