When you increase your depth under water, the water pressure on your body
increases
decreases
stays the same
How do you Calculate Pressure
Force(N)/Area(m2)
Force(kg)/Area(mi2)
Area(m2)/Force(N)
Why won't you sink in mud if you wear boots?
Because the surface area is larger creating less pressure.
Has air in it to keep you floating.
Because the mud won't want you.
Diagram shows the design of a dam. Why does the thickness of the dam increase with its depth?
The design of this structure is stronger.
Water pressure increases with depth.
The cost of construction is lower.
Water pressure acts uniformly in all directions.
What is pressure?
The amount of force exerted on a surface
The surface area of an object
The weight of an object
Pressure can be exerted by solids, liquids and gases.
TRUE
FALSE

Increased
Decreased
Not changing
The pressure exerted by a liquid
increases with depth.
decreases with depth.
is constant
first increases and then decreases.
The diagrams show, to the same scale, the vertical sections of a set of circular vessels, each containing the same depth of water.
The water exerts the same pressure on the base of each vessel.
The water exerts the greatest pressure on the base of vessel S.
The water exerts the greatest pressure on the base of vessel P.
The water exerts the same force on the base of each vessel.
