3. 100 200 400 300 400 Pressure Transmitting Forces in a Fluid Floating and Sinking Bernoulli’s Principle 300 200 400 200 100 500 100

4. Row 1, Col 1 Pressure equals force divided by this (What is Area)?

5. 5,2 This is an example of a Hydraulic System. (What are brakes, backhoe, etc.)?

6. 1,3 You would float higher in the Great Salt Lake because of this (What is the water is more dense and has greater buoyancy.)

7. 1,4 A faster moving fluid creates this (What is lower pressure)?

8. 2,1 a substance that can easily flow such as a liquid or a gas. (What is Fluid)?

9. 2,2 This multiplies a force by applying the force to a larger surface area. (What is a Hydraulic System)?

10. 2,3 If the buoyancy force is greater than the weight of the object the object will do this. (What is Float)?

11. 2,4 On an airplane wing the curved part is in this location. (What is above or on top)?

12. 3,1 As elevation increases, air pressure does this. (What is Decreases)?

13. 3,2 A 30kg box is.2m long and.15m wide. What pressure does it exert on the floor? 1.Area=lxw….2mX.15m=.03m 2 2.Force 30kgX9.8m/s 2 =294n 3. Pressure F/A 294n/.03m 2 =9800Pa

14. 3,3 According to Archimedes’ Principle, the buoyancy force is equal to the weight of this. (What is the weight of the fluid displaced)?

15. 3,4 The curved part of the wing or a spoiler causes air pressure to do this. (What is Decrease)?

16. 4,1 When you’re swimming, the deeper you go the more the pressure does this. (What is Increases)?

17. 4,2 Any pump operates on this principle. (What is Pascal’s Principle)?

18. 4,3 Why are cabins in jets pressurized? You are so high up there is not enough air to breath. The cabin is pressurized to what humans are adapted to.

19. 4,4 The spoon was drawn into the running water because the surrounding air pressure was this compared to the running water (What is Higher)?

20. 5,1 Pressure is measured in a unit called this. (What is a Pascal?)

21. 1,2 According to Pascal’s Principle, pressure in a fluid is transmitted throughout the fluid in this way. (What is Equally)?

22. 5,3 The reason a clay ball which sinks, can be re-shaped into a boat that floats is that you decrease this for the clay. (What is the Density… or Surface area?

23. 5,4 Explain how a straw works. You suck air out of the straw, creating low air pressure inside the straw/your mouth. The atmospheric pressure pushing down on the liquid is high pressure, and this forces the liquid up the tube and into your mouth.
