- What does Bernoulli's principle state?
- What does Pascal's Principle state?
- How do planes (flying disks- same concept) take advantage of Bernoulli's principle?
- How could you measure pressure?
- What is air pressure?
- a The faster the fluid moves, the less pressure it exerts within the fluid.
- b when a force applied to a confined fluid the change is pressure is equally transmitted through the fluid.
- c the earth's atmosphere is constantly applying pressure (example)
- d 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.
- e with a barometer
5 Multiple choice questions
- equal to the volume of what is submerged.
- a force that acts in the opposite direction of gravity
- chimneys, planes (flying disks), and atomizers
5 True/False questions
What is the formula for density? → force/area
What is the SI unit of pressure? → force/area
How can a ship float? → the amount of water the ship displaces increases the buoyant force and therefore has a net force greater upwards than down.
How do atomizers take advantage of Bernoulli's principle? → 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 hydraulic systems take advantage of Pascal's principle? → my multiplying the force over a greater area.
