OverviewWhat does buoyant force mean?What is Archimedes' principle?What's confusing about the buoyant force and Archimedes' principle?Example 1: (an easy one)Example 2: (a slightly harder one) Have you ever dropped your swimming goggles in the deepest part of the pool and tried to swi…So why do fluids exert an upward buoyant force on submerged objects? It has to do with differences in pressure between the bottom of the submerged object and the top. Say someone dropped a can of beans in a pool of water. [Not again!]Because pressure (Pgauge=ρgh) increases as you go deeper in a fluid, the force from pressure exerted downward on the top of the can of beans will be less than the force from pressure exerted upward on the bottom of the can.
