PPT-Chapter 13: Equilibrium and

Human Movement Basic Biomechanics 4 th edition Susan J Hall Objectives Define torque quantify resultant torques and identify the factors that affect resultant joint torques Identify the mechanical advantages associated with the different classes of levers and explain the concept of leverage within the human body. City Size. Why do cities differ in size and scope? . In this Chapter we explore the economic forces responsible for the development of cities with different sizes.. Determinants of City Size. The following factors will determine the size of a city:. Principles of Chemical Reactivity: . Equilibria. All chemical reactions are reversible, at least in principle.. The concept of equilibrium is fundamental to chemistry. . The general concept of equilibrium was introduced in Chapter 3 to explain the limited dissociation of weak acids.. 211 Review Skills Dynamic Equilibrium Dynamic Equilibrium Between Equilibrium Vapor Pressure 14.2 Boiling Liquids How Do Bubbles Form in Response of Boiling-Point Temperature to External Relative B Chemical Reactions:.

The Concept of Equilibrium. . Chemical equilibrium. occurs when a reaction and its reverse reaction proceed at the same rate. In the figure above, equilibrium is finally reached in the third picture.. Demand & Supply Together. Bringing Supply and Demand Together. How is the price of a good determined?. The market forces of supply AND demand work simultaneously to determine the price.. The law of supply and demand. . Periodic (oscillatory) motion.. Assignment. . No HW this week. . Wednesday: Read through Chapter 15.4. Periodic Motion is everywhere. Examples of periodic motion. Earth around the sun. Elastic ball bouncing up and down. Conditions . for . Static Equilibrium. Center . of Gravity. Static . Equilibrium Problems. S. tability. Last day I asked. The supports to the diving board provide a vertical force on the board so the diver will not fall. What are the directions of the force on the board at point 1 and point 2: up or down? Why?. . When the rates of the forward and reverse reactions become equal, the concentrations of the reactants and the products remain constant. This is the stage of chemical equilibrium. This equilibrium is . Read Chapter 13 look at the problems. Do . the AP practice test on page AP-13 A-D. (it is in between numbered pages 547-548). 2. AP Test. Historically, the first question on the free response has ALWAYS been an equilibrium question.. The Meaning of K. . K > 1 . . the equilibrium position is far to the right . K < 1 . . the equilibrium position is far to the left . The value of . K. for a system can be calculated from a known set of equilibrium concentrations. . LECTURE. . OUTLINE . 19.1 .
