b11 pressure test

QuestionAnswer
What is the pressure on an object equal to? force per unit area (force divided by area)
Which scientist is responsible for the principle that an increase in velocity of fluid will result in the decrease in pressure? Bernoulli
What is the pressure if the force is 100N on an area of 4m2? 25 n/m2
What happens to air pressure when you drive down from a high mountain? increases
If you are walking on snow with snowshoes, what happens to the pressure on the snow? is less
When the speed of a fluid increases, pressure? decreases
when you go deep into a pool the pressure on your ears? increases
What would cause an increase in gas pressure in a sealed, flexible container? decrease in volume
The direction of fluid pressure is perpendicular to the surface of an object
What is the SI unit for pressure? Pascal
What is pressure all around us called? Fluid pressure also called atmospheric pressure
Pressure is equal to force divided by area
What measures atmospheric pressure barometer
pressure will increase if the force increases or the area decreases
What happens to atmospheric pressure as elevation increases? decreases
Pascal's princlple states that the force (speed) on a fluid increases, pressure increases
What does wind do to the smoke coming out of the chimney? increases it.
Air at sea level is is 100,000 N
Equation used to find pressure p= f/a
barometer instrument used to measure air pressure
fluid pressure pressure in liquids and gases
buoyant force upward force that is exerted by a fluid
When air is compressed, density remians the same
a fluid is any substance with no definite shape and can flow
Atmopsheric pressure is 100,000 PA
Lift needed to make an airplane fly
density mass divided by volume
Fluid pressure pressure in gases and liquids
How much pressure is there when 300 n of force is applied over an area of 60 m2 5 n/m2
What is the pressure if the force is 90n and the area is 15 m2 6 n/m2
force = 250n , area = 75m2 what is the pressure 3.33 n/m2
what is the force if the pressure is 16n/m2 and the area is 10 m2 160 n
True or False: Air is more compressed at sea level than high altitudes. True?
Which principle states as the speed of a fluid increases, the pressure decreases Bernoulli's principle
Pascal's principle a force applied to a fluid in a closed container, pressure thoughout the fluid increases the same amount
pressure the amount for force acting on a surface p=f/a
