- How do planes (flying disks- same concept) take advantage of Bernoulli's principle?
- What can you tell about an object if you know the density?
- How do hydraulic systems take advantage of Pascal's principle?
- What is buoyancy?
- What is area measure by?
- a if it would sink or float.
- b meters squared
- c my multiplying the force over a greater area.
- d a force that acts in the opposite direction of gravity
- 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
- a material that can easily flow
- the earth's atmosphere is constantly applying pressure (example)
- when a force applied to a confined fluid the change is pressure is equally transmitted through the fluid.
- By increasing its density with water and overcoming the buoyant force by adding more weight and not changing the volume and therefore not displacing anymore water to increase the buoyant force.
5 True/False questions
As depth in water increases, pressure → decreases
What is pressure measured by? → meters squared
What is the SI unit of pressure? → Pascals
what is the formula for pressure? → mass/volume
What is the formula for density? → mass/volume
