## Buoyant Force Equation: Step-by-Step Derivation (11:04)

In this physics lesson, we dive into the concept of buoyant force by analyzing a hypothetical cube submerged in a fluid. We derive the equation for buoyant force, which is the upward force exerted on an object in a fluid, equal to the weight of the fluid displaced by the object. Through a detailed analysis, we show that the composition of the object does not affect the buoyant force, only the mass of the fluid displaced and the gravitational field strength.
