Here is an excellent working model that depicts how submarines are able to dive deep below the sea and come back up to surface of the water by changing their buoyancy.
When an object is placed in a fluid, such as a liquid or gas, the object’s weight is opposed by the upward force that results from the displacement of the fluid by the object. This upward force is called buoyancy.

Here is an excellent working model that depicts how submarines are able to dive deep below the sea and come back up to surface of the water by changing their buoyancy.
When an object is placed in a fluid, such as a liquid or gas, the object’s weight is opposed by the upward force that results from the displacement of the fluid by the object. This upward force is called buoyancy.
Submarines are able to “float” in water because of buoyancy. The weight of the ocean water that is displaced by a submarine is equal to the weight of the submarine. The buoyant force that is created by the submarine is enough to overcome the downward pull of gravity on the submarine. By controlling its buoyancy, a submarine can control its depth within the ocean waters.
