Calculate Buoyant Force
Formula
Fb = ρ_fluid × V × g, where ρ is fluid density, V is submerged volume, and g = 9.81 m/s².
Frequently Asked Questions
What is Archimedes' Principle?
Archimedes' Principle states that the buoyant force on a submerged object equals the weight of the displaced fluid: Fb = ρ_fluid × V_submerged × g.
How do I know if an object floats?
An object floats if the buoyant force exceeds its weight, or equivalently, if the object's average density is less than the fluid's density.
