- a the wind on top of the chimney creates a lower pressure at the top, on the bottom is a greater pressure which forces the smoke and heat to rise

How do planes (flying disks- same concept) take advantage of Bernoulli's principle? → the shape of their wings are curved on the top which creates a greater distance and air has to cover to match the speed of the bottom of the wing. Therefore, the fluid on the top of the wing moves faster and creates a lower pressure while the bottom of the wing has a greater pressure causing a lift. this lift make the wing rise and the airplane with it.
A partly submerged object displaces an amount of liquid... → equal to the volume of what is submerged.
What does Bernoulli's principle state? → when a force applied to a confined fluid the change is pressure is equally transmitted through the fluid.
What is a fluid? → a material that can easily flow
what is the formula for pressure? → mass/volume
