This document contains notes from a science class on fluids and motion taught by Ms. Sindy Rivera. The notes discuss several principles including Bernoulli's principle which states that as the speed of a moving fluid increases, the fluid's pressure decreases. It also covers factors that affect flight like speed, design, and shape. Additional topics summarized are lift, thrust, how wing size affects lift, how Bernoulli's principle applies to birds and baseball, drag and its effect on motion in fluids, turbulence and how it can reduce lift, Pascal's principle and how it transmits pressure changes equally, and how Pascal's principle is used in hydraulic devices.
Fluids in Motion
- 1. DEL VALLE BILINGUAL INSTITUTE Fluids and Motion Science Ms. Sindy Rivera Members: Alejandra Peñalva Faith Bustillo Juliana Chavez Myrka Barahona Christian Zuniga Michael Hernandez
- 2. FLUID SPEED AND PRESSURE Bernoulli’s principle states that as the speed of a moving fluid increases, the fluid’s preasure decreases.
- 3. This principle can also be applied by using water. This occurs because water is moving faster than the air around it.
- 4. Factors That Affect Flight Speed: This means a difference in pressure. The result is an upward force. Design: Air speed is above the wing is greater than speed below the wing. Shape:Air pushes wing upward.
- 5. Lift is an upward force on an object that moves in a fluid.
- 6. Thrust and lift Thrust is the pushing or pulling force excerted by the engine of an aircraft or rocket.
- 7. Wing Size, Speed, and Lift The amount of lift also depends on the size of the plane’s wings.
- 8. Bernouilli and Birds Birds dont have engines, so birds must flap their wings to push themselves through the air.
- 9. Bernoulli and Baseball Bernoulli principle can be also applied in baseball. Here we can see how curveball path works.
- 10. Drag and Motion in Fluids Drag is the force that opposes or restricts motion in a fluid.
- 11. Turbulence and Lift Lift is often reduced when turbulence causes drag.
- 12. Pascal’s Principle Pascal principle states that a change in pressure at any point in an enclosed fluid will be transmitted equally to all parts in a fluid.
- 13. Pascal’s Principle and Motion Hydraulic devices use Pascal’s principle to move or lift objects.
