🔍 Key Concepts

• Archimedes' principle and what makes an object float • Difference between buoyancy and deadweight • What freeboard and midships strength actually describe on a ship

💭 Think About

• Ask yourself: If I lower a ship into the water, what physical effect is buoyancy directly opposing? • Which choice describes a ship’s capability or condition in the water, rather than a structural characteristic or a measured load? • Which terms in the options are more about weight carried, structural strength, or distance above water, rather than the floating force itself?

✅ Before You Answer

• Be clear that deadweight is related to how much a ship can carry, not why it stays up. • Remember that freeboard is a vertical distance on the hull, not a force. • Confirm which option directly relates to the upward force from displaced water that keeps the ship from sinking.
