You hold a piece of wood in one hand and a piece of iron inthe other. Both pieces have the same volume, and you holdthem fully under water at the same depth. At the momentyou let go of them, which one experiences the greater buoyancy force?(a) The piece of wood.(b) The piece of iron.(c) They experience the same buoyancy force.(d) More information is needed.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
You hold a piece of wood in one hand and a piece of iron in
the other. Both pieces have the same volume, and you hold
them fully under water at the same depth. At the moment
you let go of them, which one experiences the greater buoyancy force?
(a) The piece of wood.
(b) The piece of iron.
(c) They experience the same buoyancy force.
(d) More information is needed.
