1. Chapter 3 Notecards

2. What is the formula for pressure? Force/Area

3. What are the units for pressure? (Not the guys name) N/M²

4. At higher elevations the air pressure is _________________ compared to the air pressure at lower elevations Lower

5. An object under water feels lighter than it does in air because of Buoyancy

6. Pressure spreading equally to all parts of a confined fluid is an example of __________ principle Pascal’s

7. If an object is dropped into a beaker full of fluid and sinks. What can you say about that objects density? The objects density is greater than the fluid

8. If fast moving air passes between two balloons, the balloons will…… Move together

9. The air moves more quickly against the curved top edge of aircraft wing compared to the bottom edge. This causes the plane to Rise (Increase Elevation)

10. Bubbles rise in soda because The bubbles are less dense than the soda

11. Pumps such as your heart work because of ____________principle Pascal’s

12. A device that increase force due to pressure is called a _______ device. Ex. Brakes Hydraulic

13. Mass per unit volume is the definition for this term Density

14. The faster that a fluid is moving past the object, the _________the pressure will be Less

15. The pressure exerted by the gas in the Earth’s atmosphere is called Air or Atmospheric Pressure

16. A fluid is a substance whose _________can easily change Shape

17. Water pressure _________ with depth increase

18. Buoyant force always works in this direction Upward

19. The weight of displaced fluid = the buoyant force of an object is _______________ principle Archimedes' principle
