What is Archimedes' principle?
Archimedes' principle states that the buoyant force on a submerged object equals the weight of the fluid it displaces, calculated as F = ρVg, where ρ is fluid density, V is displaced volume, and g is gravitational acceleration.
Why do some objects float while others sink?
An object floats if its average density is less than the fluid's density, and sinks if it's greater — this determines whether the buoyant force can support the object's weight.
