Define pressure - how does it differ from force?
If the same force is applied to twice the area,
what happens to the pressure?
If the pressure of the atmosphere is about
15 pounds per square inch, and the top of your
car is about 50 inches by 50 inches, what
total force is exerted on the top of your car
by the atmosphere? Why doesn't it crush the
car top in?
How do you find the pressure at a depth in a fluid?
If you dive to a depth of 10 meters, how much
additional pressure is exerted upon you?
What is Pascal's Principle?
What is a hydraulic press and what is it
good for? How is Pascal's Principle used
in the hydraulic press?
Can a hydraulic press multiply force? Can
it cause something to move further than the
force which is applied to the press? Can it
do both at the same time?
What is the Bernoulli Principle?
Is there really such a thing as a curveball pitch in
baseball, or is it an optical illusion? How can the
Bernoulli Principle cause a ball to curve?
What is Archimedes' Principle?
What was the basis for Archimedes' conclusion
that the king's crown was not made out of
How can you make use of the buoyant force on an
object to determine its density?
If your heart were not pumping enough blood through
an artery to supply your body's needs, what could be
changed to increase the flowrate?
If you could increase the blood pressure by 10%, or
increase the radius of the artery by 10%, which
would be more effective in increasing blood flow?
If an artery started to expand because its
wall was too weak to withstand the
internal blood pressure, would that
expansion relieve the stress or tension
of the artery wall?
What is the origin of the force which pushes
the mercury up in a barometer?
What force pushes a liquid up a drinking straw?
What force moves air into your lungs when
