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
