what is a buoyant force
The buoyant force. When an object is placed in a fluid, the fluid exerts an upward force we call the buoyant force. The buoyant force comes from the pressure exerted on the object by the fluid.Because the pressure increases as the depth increases, the pressure on the bottom of an object is always larger than the force on the top-hence the net upward force.The buoyant force is present whether the object floats or sinks.hen an object is placed in a fluid, the fluid exerts an upward force we call the buoyant force. The buoyant force comes from the pressure exerted on the object by the fluid.
