The buoyant force does not get smaller as you sink

WebSubmarines are large, heavy ships that are often built with steel, so how do they float in the water? The answer is buoyancy. A submarine or a ship displaces a weight of water equal to the weight of the ship. This displacement of water creates an upward force, opposite to the pull of gravity, called the buoyant force.
