🔍 Key Concepts
• KG in stability refers to a distance measured from a fixed reference point on the ship
• Relationship between G (center of gravity), B (center of buoyancy), K (keel), and M (metacenter)
• Difference between a point (G, B, M) and a distance (KG, KB, KM, GM)
đź’ Think About
• Which letter in KG refers to the specific point whose height you are measuring?
• From what reference point are most ship vertical distances (like KB, KM, KG) usually measured?
• Look at each option and decide: is it describing a point (location) or a distance (height)? KG is which of these?
âś… Before You Answer
• Identify which options describe a height/distance rather than a single point
• Recall that G = center of gravity, B = center of buoyancy, M = metacenter, K = keel
• Verify which option correctly states: "height of [which point] above [which reference]" that matches the notation KG
