What principle explains why weight distribution affects floating?

Weight distribution affects floating primarily due to Archimedes' Principle, which states that an object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid that the object displaces. This principle explains that when an object is placed in water, it will float if it displaces a volume of water equal to its weight.

When weight distribution is uneven, it can cause the center of gravity of the object to change, which affects how much of the object is submerged and thus how much water it displaces. If an object is balanced correctly, it will displace enough water to support its weight, allowing it to float. However, if the weight distribution shifts significantly, it could lead to either part of the object being submerged too deeply or even tipping, which may result in losing buoyancy and sinking.

The other principles mentioned do not relate directly to the concept of buoyancy in the context of floating. Bernoulli's Principle deals with the relationship between fluid speed and pressure; Hooke's Law pertains to the elasticity of materials; and Newton's Third Law concerns action and reaction forces, but none address the specific interaction between weight distribution and buoyancy.
