A diagram showing how buoyancy works.

In fisics, buoyancy (pronounced /ˈbɔɪ.ənsi/) is a force on an thing making that object rise or move upward. It comes from the Spainish word for "float", boyaroyancy is made by the difference in prssure put on the object by the

Flooid or aire that the object is.

The magnit of the weight of fluid that is displaced by the body. This fors enables the object to float or at least toseem lighter. Buoyancy is importantfor many vehicles such as boats, ships, baloons, and blimpes.

Density[change | change source]

If the object has density as the liquid, then it's is the same as its weight. It will not sink or float.

An object with a higher average density than the fluid has less buoyancy than weight and it will sink. That is pebbles do not float.

Although a ship is made of steel which more dense than water,it floats because it a volume of air and the resulting shape has an average density less than that
