"when a ship goes from the ocean into a lake, it will,"
Float lower in the water and require the same buoyant force to stay afloat.
I understand that the lake water is less dense than the ocean water, so the ship will sink further below the surface because its density is closer to that of the lake water. For that reason, it will displace more water. The buoyant force is defined as the mass of the volume of water displaced. My thinking was that since the lake water is displaced more, there is more mass, so the buoyant force would be increased.
However, I realize that I did not consider the fact that the density is different. Could someone explain to me how this works out? How are the masses of the two amounts of water the same?
I tried writing two equations to see it, but it doesn't really make sense
Densitysea = mass sea / volume sea
Density lake = mass lake / volume lake
In each, I guess density of sea and volume of lake would be increased, and somehow their masses would be the same.........
