Hi Lim00b,

I am not that good in science. I only know everything has buoyancy. If it has buoyancy it will float. Are you saying buoyancy is the upward force the object up? Where did this force come from?

Water displacement.

The lifting force of the ship in the water is depended how much water displacement, so the larger the ship area that displaces the water, the larger the force is.
