Buoyancy
11
⚡ Quick Summary
Buoyant force equals the weight of the fluid displaced by an object.
Buoyant force = Vρg, where V is the volume of the fluid displaced, ρ is the density of the fluid, and g is the acceleration due to gravity.
When an object is immersed in a fluid, it experiences an upward force called the buoyant force. This force is equal to the weight of the fluid displaced by the object. The buoyant force affects the net force on the object, influencing whether it floats or sinks.
