5 Written questions

5 Matching questions

  1. What does Bernoulli's principle state?
  2. What does Pascal's Principle state?
  3. How do planes (flying disks- same concept) take advantage of Bernoulli's principle?
  4. How could you measure pressure?
  5. What is air pressure?
  1. a The faster the fluid moves, the less pressure it exerts within the fluid.
  2. b when a force applied to a confined fluid the change is pressure is equally transmitted through the fluid.
  3. c the earth's atmosphere is constantly applying pressure (example)
  4. 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.
  5. e with a barometer

5 Multiple choice questions

  1. equal to the volume of what is submerged.
  2. a force that acts in the opposite direction of gravity
  3. chimneys, planes (flying disks), and atomizers
  4. decreases
  5. Newtons

5 True/False questions

  1. What is the formula for density?force/area


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


  3. 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.


  4. 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


  5. How do hydraulic systems take advantage of Pascal's principle?my multiplying the force over a greater area.
