Check out the full fluids playlist here: https://www.youtube.com/playlist?list=PLSQl0a2vh4HC7tmkuYc7nD8vIn2mOKQFS The buoyant force is a net upward force exerted on an object by a fluid. The buoyant force results from the increase in fluid pressure with depth. The magnitude of the buoyant force exerted on an object by a fluid is equal to the weight of fluid displaced by the object (ρVg).
