Total questions: 9
Worksheet time: 5mins
What principle states that as the speed of a moving fluid increases, the pressure exerted by the fluid decreases
buoyant force
Bernoulii's Principle
Pascals Principle
Archimede's Principle
Why is air pressure at the top of a chimney less than air pressure at the bottom
The top is skinny and the bottom is bigger so air is more air pressure for the bottom getting to the top
Wind blowing across the top of a chimney creates an area of low pressure
So there is no smoke in the room but it goes up insteaf
So the smoke isn't flying out
What does the Bernoulli's Principle help explain
How planes fly
Smoke in Chimney
Flying disk gliding throigh the air
Helium helping balloons flying through the air
Where is high presure located
At the bottom
in the middle
at the top
outside of the bottle
Does lift have an upward force or downward force
(a)
What is the best depiction of Bernoulli's principle below?
As the pressure of a fluid decreases, the speed increases
As the pressure of a fluid increases, the speed increases
As the pressure of a fluid decreases, the speed decreases
