100
a force exerted in a surface
What is pressure?
100
another word for air pressure
What is atmospheric pressure?
100
the ability to float
What is buoyancy?
100
the definition of Pascal's principle
What is when force is applied to a confined liquid, the change in pressure is transmitted equally to all parts of the fluid?
100
three things that use Bernoulli's principle
What are airplanes, smoke up a chimney, an atomizer
200
the formula for calculating pressure
What is Pressure = Force / Area?
200
this happens as your elevation increases
What is atmospheric pressure decreases?
200
the acts in a opposite the force of gravity and makes things feel lighter
What is buoyant force?
200
how a hydraulic system works
What is multiplies force by applying the force to a small surface area which is transmitted through liquid to a larger surface area?
200
the definition of Bernoulli's principle
What is as the speed of the fluid increases, the pressure within the fluid decreases?
300
the unit of measurement equal to 1N/m2
What is Pascal?
300
this happens as depth increases
What is water pressure increases?
300
Archimede's principle
What is the buoyant force is equal the weight of the fluid that the object displaces?
300
two examples of hydraulic systems
What are brakes and lifts?
300
during the paper experiment, where the pressure was greater
What is below the paper?
400
this is equal to the pressure exerted by a fluid
What is all of the forces exerted by the individual particles of the fluid?
400
the instrument used to measure atmospheric pressure
What is a barometer?
400
the formula for density
What is density = mass/volume?
400
how large the right piston must be to multiply the force applied to the left piston 5 times
What is 5 times the area of left side?
400
this is what causes lift on an airplane
What is the shape of the wing that causes air to move faster above than below?
500
this happens to pressure if the same force is exerted on a smaller area
What is pressure increases?
500
one of these exerts more pressure, a woman in high heels or a woman in work boots
What is the woman in high heels?
500
the density of water
What is 1 g/cm3
500
what direction is the fluid pressure in an enclosed liquid
What is all directions?
