how do ships float?

Question

i know it has to do with bounancy but give me a more simple answer

Answer 1

dont know

Answer 2

Ah, time for a gedanken-experiment!

Imagin pushing the bottom end of a clear glass partway into a bowl with water in it. You can feel the glass pushing back against your hand. You can see the water outside the glass through its sides. You can see air in the bottom of the glass. Imagine that the glass has water inside it, up to the same level as the water outside the glass.

The pressure you felt against your hand was the glass's bouyancy - it's tendency to float. It was bouyant because it weighed less than the water it displaced. Anything lighter than the water it displaces floats - like wood, or a boat. Anything heavier than the water it displaces sinks.

A boat floats because it displaces more water than what the boat weighs. If you put a hole in the bottom of a boat, the water comes in. Suddenly, not only does the boat displace less water (because the water is inside what used to be a hole in the water), but the water inside the boat is added to the weight of the boat already. When you get enough water inside, the whole combination of boat and water weighs more than the water it displaced, and it heads for the bottom.

Answer 3

If the ship displaces a volume of water that is greater than the weight of the boat itself, it floats.

Answer 4

its not bouyancy.
steel is not bouyant, neither is concrete, which is used in Texas A&M's concrete boat contest.

its displacement.
if you displace enough water, you can make anything float.
the more water you displace, the more pressure you have UPWARD against the hull of a ship or object.
thats how they make steel and concrete float.

Answer 5

The ship's weight is less than the weight of an equal volume of water that they are displacing.

Answer 6

bouyant force
