What is the buoyant force?
💡 Hint: Consider what keeps an object afloat in water.

Challenge Problems
Push your limits with advanced challenges
Calculate the metacentric height of a boat that has a center of buoyancy that moves up by 0.2 meters when tilted and has a center of gravity at 1 meter above sea level.
💡 Hint: Remember: BM > BG for stability.
A floating object tips slightly, moving its center of gravity upward, potentially affecting stability. How would you experimentally determine if the object is stable or unstable?
💡 Hint: Observe and test the recovery behavior after the tilting.
