PPT-Chapter 11: Forces in Fluids

112 Floating and Sinking Buoyancy the ability to float buoyant force acts in a direction opposite gravity so it makes an object feel lighter O k Lets make sure we understand what is going on . And 57375en 57375ere Were None meets the standard for Range of Reading and Level of Text Complexity for grade 8 Its structure pacing and universal appeal make it an appropriate reading choice for reluctant readers 57375e book also o57373ers students A force is a . conservative force. if the net work it does on a particle moving around any closed path, from an initial point and then back to that point, is zero. . Equivalently, a force is conservative if the net work it does on a particle moving between two points does not depend on the path taken by the particle. . Classification of Non-Newtonian Fluids. Laminar Flow of a Non-Newtonian fluid in Circular Pipes. Recommended text-book: W.F. Hughes, J.A. Brighton, . Schaum's. outline of theory and problems of fluid dynamics, New York: McGraw Hill, 1999. CA Standards. Students know . the atoms and molecules in liquids move in a random pattern relative to one another because the intermolecular forces are too weak to hold the atoms or molecules in a solid form.. A . force. is a push or a pull. .. Many different forces act on objects around us all the time.. . If . the forces on the object are . balanced. , . then the object doesn’t move. . When two or more forces are acting on an object and they are not equal in size, we say the forces are . 11.1: Forces change motion. 11.2: Force and mass determine acceleration. 11.3 Forces act in pairs. 11.4 Forces transfer momentum. Warm-up Questions (T or F). Speed includes direction, while velocity does not. ● . Phases and Phase Diagrams. ● Liquids and Liquid Properties. ● Intermolecular Forces. ● Heating Curves. ● Introduction to Solids. ● Cubic Packing Arrangements. ● Closest-Packed Structures. Jazz . Slappey. Ms.Carter. 5. th. Grade. December 1, 2015. What are Constructive Forces?. Constructive Forces are processes that help build or construct the Earth.. Constructive forces can deposit soil or silt in a river.. Chemistry 11. Ms. McGrath. Intermolecular Forces. The forces that bond . atoms. to each other within a molecule are called . intramolecular forces. . Covalent bonds and ionic bonds are an example of intramolecular forces.. the forces between (among) individual particles (atoms, ions, molecules); they are weak relative to . intramolecular. forces (i.e. covalent and ionic bonds within a compound). Intermolecular forces are increasingly significant in this order:. Viscosity is how engineers measure the resistance of fluids when being . deformed:. τ. = . μ. (du/dy. ). The less viscous the fluid, the greater its ease of . movement.. Viscosity is useful for calculating the force needed to move a fluid. For example, in these industries: . Science Question of the Day . What causes the noise when you crack your joints?. _________________________________. _________________________________. _________________________________. Gravity . Gravity is a specific kind of _____________.. Experiment associated with Blaise Pascal. A long thin tube placed into a barrel. Water . is poured in the top that increases the . Hydrostatic Pressure based on elevation. and causes the barrel to burst. . . Review: Forces. What is a force? . Why do you think it’s important to learn about forces? What about gravity and friction?. How might an understanding of forces help you in your everyday life? .
