What is Buoyancy?

Buoyancy is the tendency of an object to float in a fluid. When immersed, the object experiences two forces - an upward buoyant force by the fluid and a downward weight due to gravity. It floats if the buoyant force is larger else it sinks.

What is Buoyant Force?

Buoyant force is the upward force exerted by a fluid on an immersed object. The buoyant force depends on the fluid's density, volume of the fluid displaced by the object and the acceleration due to gravity. Surprisingly, the depth of the object submerged has no effect on it.

How to calculate the Buoyant Force?

Buoyant force is calculated by the formula Fbuoyant = ρ × V × g , where ρ is the density of the liquid the object is immersed in, V is the volume of the displaced liquid and g is the gravitational acceleration.
