8th grade science:physical sceince

the pressure caused by the weight of the atmosphere atmospheric pressure
a nonsolid state of matter in which atoms or molecules are free to move past each other, as in a gas or liquid fluid
the amount of force exerted per unit area of a surface pressure
the SI unit of pressure pascal
the upward force that keeps an object immersed in or floating on a liquid buoyant force
the principle that states that the buoyant force on an object in a fluid is an upward force equal to the weight of the volume of fluid that the object displaces Archimedes' principle
the principle that states that the pressure in a fluid decreases as the fluid's velocity increases Bernoulli's principle
which principle cam explain how a hydraulic device works Pascals principle
which principle could you use to determine if an object will float in water Archimedes principle
which principle can help explain how a bird flies Bernoullis principle
what will happen if the buoyant on an object is greater than the weight of the object the object will be pushed out of the fluid(buoyed up)
as a person climbs a mountain, the atmospheric pressure he or she feels will decrease
a bicycle tire goes flat if it has a hole because the air inside the tire is at a higher pressure than the air outside the tire
aluminum has a higher density than water, but an empty aluminum can floats in water.why does the can float the air inside the can makes the overall density of the can less than the density of water
which of the following affect the flight of an airplane drag,lift,thrust
how is lift created around the wing of an airplane faster-moving air above the wing creates an area of low pressure above the wing
how does the water pressure change as you dive farther underwater it increases
the SI unit for pressure is called______ and is equal to 1 N/m2 Pascal
presssure can be calculated by dividing force by ______ area
the upward force exerted by fluids on matter is called the ____________ buoyant force
submarines and some fish can control their depth underwater by changing their________ density
the upward force that keeps planes and birds aloft is called______ lift
