WebNov 3, 2024 · One way a submarine can sink is if it loses buoyancy. This can happen if the submarine takes on water, either from the sea or from leaks in the hull. The weight of the water makes the submarine more dense, and it will eventually sink. Another way a submarine can sink is if it is damaged and begins to take on water.
The buoyant force does not get smaller as you sink
WebApr 8, 2024 · As gravity pulls down the submarine, water creates an opposite upward force called buoyant force which prevents the ship from sinking. Complete answer: Submarines contain tanks called ballast and trim tanks. These ballast and trim tanks are filled with water and air accordingly for the submarine to sink or float in water. WebThe submarine is normally trimmed to near neutrally buoyant. This is done by fully flooding the main ballast tanks and then adjusting the amount of water in the auxiliary ballast tanks (aka trim tanks). The submarine is ‘driven’ to the desired depth using the control surfaces much like an airplane changes elevation. philthy rich youtube
How do submarines sink below the water and then rise?
WebSubmarines sink by taking in ocean water into large tanks. This weighs them down, allowing them to sink. They take in as much as they need to go as low as they want to.

WebThe submarine thus requires a propeller that acts together with gravity to make the submarine sink, despite the buoyant force acting on it. Another way of thinking about this is to realize that the submarine floats because it is less dense than the surrounding water. Even … philthy vintage
