Presentation Transcript

  1. Fluids • Particles are free to move past each other • Gases and liquids

  2. Archimedes

  3. Eureka!

  4. Why do things feel lighter when they are under water?

  5. Buoyant Force • Fluids exert an upward force on submerged objects • Objects weigh less

  6. Demo

  7. Archimedes’ Principle Buoyant force = weight of fluid displaced

  8. Archimedes Example • Gas bladder (swim bladder) in fish • To attain neutral buoyancy

  9. Imagine…driving in the mountains or flying in an airplane…what happens to your ears?

  10. Pressure in Fluids Constant movement of particles exerts pressure as they collide with a surface

  11. Pascal’s Principle • Pressure applied to fluid in a closed container is equally transmitted to all parts of the fluid and the container. • Think toothpaste…

  12. Applications of Pascal’s Principle… • Hydraulic lifts – auto shop, barber chair, etc.

  13. Magic Paper • Hold a piece of notebook paper just under your lower lip and blow across it. • What do you observe?

  14. Bernoulli’s Principle The pressure in a fluid decreases as the fluid’s velocity increases.

  15. Fluid Mini-Labs
