5 Written questions

5 Matching questions

  1. How can a ship float?
  2. What is air pressure?
  3. How do chimneys take advantage of Bernoulli's principle?
  4. How do atomizers take advantage of Bernoulli's principle?
  5. What is area measure by?
  1. a 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.
  2. b the amount of water the ship displaces increases the buoyant force and therefore has a net force greater upwards than down.
  3. c meters squared
  4. d the earth's atmosphere is constantly applying pressure (example)
  5. e 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 Multiple choice questions

  1. if the buoyant force is greater than gravity (weight)
  2. a material that can easily flow
  3. a force that acts in the opposite direction of gravity
  4. 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. Pascals

5 True/False questions

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

          

  2. What is pressure measured by?Newtons

          

  3. What are some examples 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.

          

  4. As depth in water increases, pressuredecreases

          

  5. How could you measure pressure?the earth's atmosphere is constantly applying pressure (example)
