5 Math is the language of physics. Mr. T s Problem Solving Strategy a.k.a. G.U.E.S.S. Method 1. Read the problem. Seriously, actually READ the problem all the way through! 2. Annotate (that means underline or highlight) the important information. 3. Identify and chart the known and unknown values. 4. Determine which formula you need to solve the problem. 5. Isolate the unknown variable on one side of the equal sign. 6. Insert the known values into the formula. 7. Solve the problem.

6 Foot Inch Yard Mile

7 Fundamental Units

8 Use units to check your work. Units tell you if formulas are set up correctly. Conversion factors 1000m = 1km, 1 = 1km, 1 = 1000m 1000m 1km

9 Convert 472 grams to kilograms. 472g x 1kg 1000g = 0.472kg

10 Convert 32.1 miles per hour (mi/h) to kilometers per second (km/s) o hint: 1m = 3.28ft, 1mi = 5280ft 32.1 mi h 5280ft x 1mi x 1m 3.28ft x 1km 1000m x 1h 60min x 1min 60s = km s

11 Convert 2.67 liters to milliliters Convert 3.61 yards to meters (1 inch = 2.54 cm)

12 Accuracy o The closeness of a measurement to its actual value. Precision o The closeness of a measurement to other measurements obtained in exactly the same way.

13 Digits from 1-9 are always significant. Zeros between nonzero digits are significant. Zeros to the right of the decimal and a significant figure are significant. Zeros used for placing the decimal point are not significant.

14 Multiplication and Division o When multiplying or dividing, the answer may only show as many significant digits as the multiplied or divided measurement showing the least number of significant digits. Addition and Subtraction o When adding or subtracting your answer can only show as many decimal places as the measurement having the fewest number of decimal places.

15 Multiplication and Division (7.2 x 10 3 ) x (3.0 x 10 5 ) 21.6 x x x 10 9

16 Addition and Subtraction (6.3 x 10 5 ) + (3.25 x 10 6 ) (0.63 x 10 6 ) + (3.25 x 10 6 ) 3.88 x x 10 6

18 Hypothesis o An educated, testable guess Scientific Theory o An explanation or model based on observation, experimentation, and reasoning. Scientific Law o A phenomenon of nature that has been proven to invariably occur whenever certain conditions exist or are met

19 Positive Observation Question Hypothesis Revise Hypothesis Experiment Negative Retest Analysis

20 Height (in.) Height of Members of the Tiesler Family Dependent Variable The variable that is measured by the researcher Independent Variable The variable that is changed by the researcher Chris Rich Ann Linda Ralph Cathy Joe Allison Steven Jose Name

21 Line graphs are used when one variable (independent) affects another, which is the dependent variable. Useful for predicting trends Continuous Data o A set of observations usually associated with physical measurement that can take on any mathematical value within specified parameters.

22

23 The data for this graph are non-numerical and discrete for at least one variable. Axes may be reversed to give a graph with the categories on the x axis. Bar graphs can be drawn horizontally or vertically. This type of graph is very useful for comparing two or more similar items. Discrete Data o Data that can only take certain values.

24

25

26 As with bar graphs, pie graphs are used when the data for one variable are discrete (categories) and the data for the other variable are in the form of counts (percentages or proportions) A circle is divided according to the proportion of counts in each category. Not suitable for data sets with a very large number of categories (more than 6)
