Pressure

the amount of force exerted on an area

Pascals

units pressure is measured in

Atmospheric pressure

pressure that results from the weight of the air that surrounds earth

Buoyant force

the force that is exerted upwards on objects in a liquid

Lift

the upward force that forms as a result of moving fluids

Thrust

forward force on an object in flight

Turbulence

irregular flow of air

Drag

a force that opposes motion in fluids

Water pressure

1,000 times more dense than air

Atmospheric pressure

the greatest at sea level

Water pressure

greatest at the bottom of the ocean

Fluid pressure always flows

from high pressure to low pressure

Fluid pressure is applied

equally in all directions

An object that has a greater buoyant force than its weight

will float

If an object has a buoyant force equal to its weight

suspend

An object submerged in water will displace a volume that is

equal to its volume

Bubbles are round

because fluids exert pressure in all directions

Atmospheric pressure doesn't crush you

because the fluids inside your body are putting out an equal amount of pressure
