- What is a fluid?
- What is pressure measured by?
- a equal to the volume of what is submerged.
- b fire truck, machines that raise cars
- c Newtons
- d a material that can easily flow
- e 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.
5 Multiple choice questions
- The faster the fluid moves, the less pressure it exerts within the fluid.
- my multiplying the force over a greater area.
- with a barometer
5 True/False questions
As elevation increases, pressure → increases
As depth in water increases, pressure → increases
What is the SI unit of pressure? → force/area
How do atomizers take advantage of Bernoulli's principle? → the flask at the top (when you squeeze it) creates a greater fluid speed which causes a lower pressure and the pressure in the bottle is greater and causes the liquid in the bottle to move up and out of the bottle.
A submerged object displaces an amount of liquid.. → equal to the volume of what is submerged.
