PPT-Forces and Fluids

Chapter 12 BIG IDEAS Newtons laws apply to all forces Gravity is a force exerted by all masses Friction is a force that opposes motion Pressure depends on force and area Fluids exert a force on objects. Here’s Tim & Mobey on Force. Brainpop. Suppose I asked you to move a heavy desk in the classroom. How would you move it? . hmmmmmmmmmmm...... You might get on one side of the desk and start pushing, Or you might grab the legs and start pulling. . Chapter . 2. Copyright © 2010 by John Wiley & Sons, Inc. All Rights Reserved.

Managers must understand the various forces that are driving these changes and affecting their businesses in order to be effective. 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: . What is a force?. A force is a push or a pull. . Forces make objects accelerate. What are the two general types of forces? How are they different?. Type 1: Contact Forces. Force as a result of object touching. 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. . To Differentiate between osmosis, diffusion, filtration and active transport.. To describe the role of kidneys, lungs and endocrine glands in regulating the body’s fluid composition and volume.. To describe the cause, clinical manifestations and . The Covenant sets out the relationship between the nation, the government and the Armed Forces. It recognises that the whole nation has a moral obligation to members of the Armed Forces and their families, and it establishes how they should expect to be treated. .
