5 Matching Questions

1. As elevation increases, pressure
2. What is pressure measured by?
3. How could you measure pressure?
4. How can a ship float?
5. How do atomizers take advantage of Bernoulli's principle?
1. a decreases
2. b Newtons
3. c with a barometer
4. d the amount of water the ship displaces increases the buoyant force and therefore has a net force greater upwards than down.
5. e 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 Multiple Choice Questions

1. if it would sink or float.
2. 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.
3. The faster the fluid moves, the less pressure it exerts within the fluid.
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. mass/volume

5 True/False Questions

1. What is area measure by?meters squared

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

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

4. A partly submerged object displaces an amount of liquid...equal to its own volume.

5. What is buoyancy?a force that acts in the opposite direction of gravity
