Buoyancy: Upward Force from Surrounding Fluid

The video explains the concept of buoyancy, where any object immersed in a fluid experiences an upward force equal to the weight of the fluid it displaces. This principle helps to understand why small dense objects like pebbles sink, while larger but hollow objects like metal ships float.

Explain the relationship between density and buoyancy.

What factors contribute to the floating of large hollow metal ships?
