Question

define buoyancy and bouyant force

Answer 1

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.

Answer 2

hey dear

here is your answer

Buoyancy -
It is an upward force which is exerted by the fluid that opposes the weight of an immersed object

fluid pressure decreaseswith the depth as a result weight of fluid overlying


Buoyant force -
It is a upthrust force in an upward direction force exerted by the fluid that opposes the weight of an immersed object

fluid increases with the depth as a result fluid is overlying at surface

hope it helps

thank you
