  1. Physics: Chp 1 Sec 2 GmanJooN

  2. SI Units

  3. Scientific Notation (sn) • Convert 94,344,000 into scientific notation. 2. 2100.25 into sn 3. Change 2.151 x 10-3

  4. Accuracy vs Precision Accuracy = how close the results are to the target or accepted value. Precision = how close the results are to each other. (the exactness of a measurement)

  5. Significant Figures The digits that are known with certainty plus the first digit that is uncertain.

  6. Sig Figs

  7. Sig Figs Calculations • Add/Subtract: Look at decimal point of the one with the least # after decimal • Multiply/Divide: Look at the least # of Sig Figs.
