Example of buoyancy using actual numbers?
That's interesting! Can you explain why the wood floats even though it's heavier than water?
Of course! The wood floats because of buoyancy. When an object is placed in a fluid, it displaces some of the fluid, which creates an upward force called buoyant force. This force is equal to the weight of the fluid displaced by the object. If the object is less dense than the fluid, then the buoyant force is greater than the weight of the object, and the object floats. In the case of wood, even though it's heavier than water, it's less dense than water, so the buoyant force is greater than its weight, and it floats.
