5 Matching questions

  1. How do planes (flying disks- same concept) take advantage of Bernoulli's principle?
  2. A partly submerged object displaces an amount of liquid...
  3. What are some example's of hydraulic lifts?
  4. What is a fluid?
  5. What is pressure measured by?
  1. a equal to the volume of what is submerged.
  2. b fire truck, machines that raise cars
  3. c Newtons
  4. d a material that can easily flow
  5. 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

  1. The faster the fluid moves, the less pressure it exerts within the fluid.
  2. my multiplying the force over a greater area.
  3. force/area
  4. mass/volume
  5. with a barometer

5 True/False questions

  1. As elevation increases, pressureincreases

          

  2. As depth in water increases, pressureincreases

          

  3. What is the SI unit of pressure?force/area

          

  4. 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.

          

  5. A submerged object displaces an amount of liquid..equal to the volume of what is submerged.
