1. A Mathematical Toolkit

2. 1.1 Mathematics and Physics What is physics? The study of the physical world How energy and matter are related

3. Does it Make Sense? Excellent way to check to see if your answer is in a suitable range

4. Base Units The foundations of the SI system All other units are derived from these seven units Meter, kilogram, second, kelvin, mole, ampere, and candela

5. Meter, m 1 st defined at 1/10,000,000 the distance from north pole to equator pass through Lyons, France 1983 light traveling in a vacuum for 1/299,792,458 s

6. Second, s First defined as 1/86,400 of a solar day Earth is slowing down so time was not constant 1960’s atomic clocks developed Now frequency of Cs-133 atom

7. Kilogram, kg Mass of small platinum- iridium metal cylinder Not reproducible with natural occurrence

8. Derived units All the other units are combinations of the base units. Newton, N is a kg. m/s 2

9. SI Prefixes Dimensional Analysis Significant Digits Scientific Notation Accuracy Precision

10. 1.3 Graphing Data Linear Relationships Nonlinear Relationships Directly proportional Indirectly proportional

11. Independent variable is the variable the experimenter changes, x- axis Dependent variable changes as a result of the independent variable, y axis
