5 Matching questions

  1. What is air pressure?
  2. What are some examples of Bernoulli's principle?
  3. What does Pascal's Principle state?
  4. How do chimneys take advantage of Bernoulli's principle?
  5. What is pressure?
  1. a the earth's atmosphere is constantly applying pressure (example)
  2. b when a force applied to a confined fluid the change is pressure is equally transmitted through the fluid.
  3. c chimneys, planes (flying disks), and atomizers
  4. d 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. e The amount of force exerted on a surface

5 Multiple choice questions

  1. decreases
  2. increases
  3. my multiplying the force over a greater area.
  4. equal to the volume of what is submerged.
  5. that the buoyant force that is acting on an object is equal to the weight of the water that is displaced

5 True/False questions

  1. How does a submarine dive?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.

          

  2. 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

          

  3. What is the SI unit of pressure?Pascals

          

  4. How can a ship float?a material that can easily flow

          

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