Name:______________________________Period:______ The Ramp (and Friction) PhET Simulation Lab go to: phet.colorado.edu/en/simulation/ramp-forces-and-motion Introduction: When an object is dragged across a surface‚ the force of friction that must be overcome depends on the normal force as F=uN and the normal force is given by N= Wy‚ the vertical component of weight pointing perpendicular to the surface. When the angle of an inclined plane changes‚ the normal force changes and so does the friction

History Colorado joined the United States of America on August 1‚ 1876 as the 38th state. In 1806‚ Colorado was discovered by Lieutenant Zebulon Pike during an expedition to determine the southwestern boundary of the Louisiana Purchase.

Basic Stoichiometry PhET Lab rvsd 2/2011 Let’s make some sandviches! _ Introduction: When we bake/cook something‚ we use a specific amount of each ingredient. Imagine if you made a batch of cookies and used way too many eggs‚ or not enough sugar. YUCK! In chemistry‚ reactions proceed with very specific recipes. The study of these recipes is stoichiometry. When the reactants are present in the correct amounts‚ the reaction will produce products. What happens if there are more or less of

Molecule Polarity PhET Lab A study of electronegativity‚ bond polarity‚ and molecular polarity Introduction: In this atomic-level simulation‚ you will investigate how atoms’ electronegativity value affects the bonds they produce. When two atoms bond‚ a pair of electrons is shared between atoms. Electronegativity is a measure of a single atom’s ability to hoard electrons shared in that bond. In this lab you will work diligently‚ at your own pace‚ to answer a number of questions. To begin‚ from

A Case of Colorado Beer – Convenience Store Advocate One may state that upon the passing of the new beer law‚ some sales in the existing liquor stores may decline. Despite this possibility‚ this can present a major expanding opportunity for all the craft beer creators in the area. As a convenience store advocate‚ I support the passage of House Bill 1192‚ which would allow grocery and convenience stores to sell full strength beer. While there are arguments on both sides for and against this Bill

The Colorado River Geographers can tell you that the one thing that most rivers and their adjacent flood plains in the world have in common is that they have rich histories associated with human settlement and development. This especially true in arid regions which are very dependent upon water. Two excellent examples are the Nile and the Tigris-Euphrates rivers which show use the relationship between rivers and concentrations of people. However‚ the Colorado River is not such a good

Gluttony took over western states such as Los Angeles‚ San Diego‚ Phoenix‚ and other fast growing cities. Oblivious to how wrong the decision to drain Colorado river’s limited resources is for such ridiculous justifications. It didn’t dawn on the people and still doesn’t. Missing all the signs Nature is suffering. The mighty Colorado River is getting drained and
