buoyant force.
The force that acts in water is called buoyancy. Buoyancy is the upward force exerted by a fluid on an object immersed in it, which opposes the weight of the object and keeps it afloat.
the air inside the can keeps it afloat
In physics, buoyancy is the upward force that keeps things afloat. The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body. This force enables the object to float or at least seem lighter.
When something floats, the buoyant force (upward force exerted by a fluid that opposes the weight of an immersed object) is equal to the weight of the object. This balance of forces allows the object to stay afloat without sinking or rising.
To find the upthrust needed to keep a 1600 N object afloat, you need to consider the weight of the object. The upthrust must equal the weight of the object for it to stay afloat, so the upthrust required would be 1600 N.
The bouyancy of the vessel keeps it afloat. As long as the force of bouyancy is larger then the mass of the ship it will stay afloat.
The water tension keeps them from sinking
When the pressure at the bottom of a submerged object is greater than the pressure at the top, a buoyant force is produced. This buoyant force is a result of the difference in pressure creating an upward force on the object, known as buoyancy, which helps keep the object afloat.
It means that the object is in the position of floating
If the object is less dense than water, the water will be able to keep it afloat. If the object is more dense than water, the water will not be able to keep it afloat, and it will sink.
