    About the Authors Robert Jansen Robert Jansen has taught Advanced Placement Physics at Aliso Niguel High School in Aliso Viejo, California, since 1998. He holds a bachelor’s degree in psychobiology from the University of California, Los Angeles, and a master’s degree in education from Pepperdine University. He gravitated toward teaching physics because of the challenging material and a sustained belief that physics does not need to be mysterious and difficult but rather can be comprehensible and achievable. The result has been a large and competitive physics program where each year more than 220 students participate in the AP Physics 1 and AP Physics C courses. The overarching goal is preparedness and confidence for students who will be studying science during their undergraduate years. Greg Young Greg Young has been teaching high school science for more than twenty years. He currently teaches Honors Physics, AP Chemistry, and Chemistry at San Clemente High School in San Clemente, California. He holds a bachelor’s degree in biochemistry from the University of California, San Diego, and a master’s degree in science education from USC. Having always been interested in science and how to make it relevant to others, Greg’s interest in teaching lies in being able to create interactive lessons that engage students in their learning and form a relevant context for difficult concepts in physics and chemistry. Science made interesting is science worth learning.

    CHAPTER 1 Conventions and Graphing Learning Objectives In this chapter, you will learn how to: © Review the fundamental metric units (SI units) and some of the derived metric units (SI units) used in physics ° Determine the dependent and independent variables of a graph > Explain the importance of slope and area to a graph Fundamental and Derived Units The fundamental metric units (SI units) in physics cover the basic quantities measured, such as length, mass, and time. The units measure a quantity and are given a unit name and symbol. Table 1.1 lists the fundamental quantities along with the unit names and symbols.

    Derived units are combinations of one or more of the fundamental units. Table 1.2 lists common derived units used in physics. TABLE 1.2 Derived Units Unit Unit Quantity (Symbol) Name Symbol Fundamental Units Density (p) Density kg/m? kg/m? Frequency (f) Hertz Hz VUs=s71 | Force (F) Newton N kg + m/s? | Energy (E) Joule J Nm = kg + m%/s? Power (P) w J/s = kg + m?/s? Pressure (P) Pascal Pa N/m? = kg/m « s2 Electric charge (q) Coulomb [¢} Ass Electric potential (V) Volt \% J/C=J/A*s=kg*m¥A-sd It is important to know which units correctly belong to a specific quantity. An easy way to do this is to write out the principal formula for the quantity and then replace each variable on the right side of the equation with its unit symbol. There may be more than one correct answer including the unit symbol, other derived units, and fundamental units. For example, all of the following are correct ways to express units of energy: J, N « m, and kg * m?/s? EXAMPLE 1.1 Study

    Derived Units The unit of force is the newton. What are the fundamental units that make up the newton? WHAT’S THE TRICK? Write down the foundational formula for force. 2 F=ma Replace the variable symbols with their matching units. Force is measured in newtons, N. Mass is measured in kilograms, kg. Acceleration is measured in meters per second squared, m/s2. N=kg- m/s? . . Graphing Variables The graphing techniques of mathematics are used in science to compare dependent and independent variables. In mathematics, you are familiar with the traditional x- and y-coordinate axes. In science, the x-axis represents the independent variable and the y-axis represents the dependent variable. The value of the dependent variable depends upon the independent variable. Graphs are always titled so that the dependent variable is listed first, and the independent variable is listed second. As an example, a position versus time graph would have position (dependent variable) plotted on the y-axis and time (independent variable) plotted on the x-axis. Slope and Area Slope Slopes are very important in physics. Slope is determined by dividing the rise (y-axis value) by the run (x-axis value). The trick is to look at the units written on the axes of the graph. If you divide these units, you can easily + StudyXY
