Significant digits (not a huge deal like in chemistry) Appendix B  \n2. Scientific notation – Appendix A  \nScientific Notation  \n• Writing very large (much greater than 1) and very small (much less than 1) numbers is cumbersome and does not make clear how many significant figures are involved.  \nMAKE SURE YOU PAY CLOSE ATTENTION TO THIS…  \n• Using scientific notation with your calculator Scientific calculators all have some kind of scientific notation button . The purpose of this button is to enter numbers directly into scientific notation and make sure the calculator stores them as a single number instead of a math equation . (This prevents you from making PEMDAS errors when working with numbers in scientific notation on your calculator.) In this class we will ALWAYS USE THE EE button on your calculator – pressing EE replaces inputing x 10. Notice that when you enter EE on your calculator (depedning on the model) your calculator may only show one E – this is completely fine. DO NOT ENTER X 10 on your calculator EVER IN THIS CLASS – hopefully I made this clear =)  \nExample: 3.82 x 10-16 x 3.0 x 10 8  \nYou enter 3.82 EE-16 x 3.0 EE 8 ENTER The calculator answer should read 1.14E-7 You write 1.14 x10 -7 (the E is replaced with x 10 )  \nMeasurements and Significant Figures  \n• When we measure any quantity we can do so with only a certain precision.  \n• We state our knowledge of a measurement through the use of significant figures: digits that are reliably known.  \nSignificant Figures  \n• Exact numbers have no uncertainty or error ex: the 100 used to calculate percentage  \nex: the 2 in the equation c = 2π r  \n• Measured numbers have some degree of uncertainty or error.  \n• When calculations are done with measured numbers, the error of measurement is propagated, or carried along.  \n• The number of significant figures (or digits) in a quantity is the number of reliably known digits it contains.  \n• There are some basic rules that can be used to determine the number of significant digits in a measurement.  \nSignificant Figures  \n• Definition: All the valid digits in a measurement, the number of which indicates the measurement’s precision (degree of exactness) .  \n• also called significant figures, or sig figs  \n• Use the Atlantic & Pacific Rule to determine the sig figs.  \nPACIFIC OCEAN  \nATLANTIC OCEAN  \n• Decimal is Absent   \n– Count from the Atlantic side from the first non-zero digit.  \n• Decimal is Present   \n– Count all digits from the Pacific side from the first non-zero digit.  \nSignificant Figures  \nExamples:  \n421  \nDecimal is absent-> Atlantic; three significant figures  \n421 000  \nDecimal is absent-> Atlantic; three significant figures  \n42.100  \nDecimal is present-> Pacific; five sig figs  \n4.201  \nfour sig figs  \n0.421  \nthree sig figs  \n0.000421  \nthree sig figs  \nTo eliminate doubt, write the number in scientific notation.  \n4.2100 x 105 – five sig figs  \n4.21 x 105 – three sig figs  \nA bar placed above a zero is also acceptable.  \n4, 210, 000 – five sig figs  \n4, 210, 000 – seven sig figs  \nTo avoid confusion, for the purpose of this course we will consider numbers with trailing zeros to be significant.  \nex: 20 s has two sig figs, even if it is not written as  \n2.0 x 101 s  \n• When you perform any arithmetic operation, it is important to remember that the result never can be more precise than the least-precise measurement.  \n• The final result of an addition or subtraction should have the same number of decimal places asthe quantity with the least number of decimal places used in the calculation.  \nExample: 23.1  \n4.77  \n125.39 +  3.581  \n156.841 Round to 156.8 (one decimal place)","cbCaipqYMHzTDlym","https://ap.wps.com/l/cbCaipqYMHzTDlym","pdf",1240045,32,"English","# Unit 1 Math Review AP Physics\n## Topics in the packet\n## Scientific Notation\n## Measurements and Significant Figures\n## Atlantic & Pacific Rule\n## Rounding in arithmetic operations","[{\"question\":\"What is scientific notation and why is it used in this course?\",\"answer\":\"Scientific notation makes it easier to write very large and very small numbers while keeping track of significant figures.
