  1. SI Base Quantities and Units

  2. Metric(SI) Prefixes

  3. Chapter1:Length 1m  10-7 of the distance from the equator to the pole 1m = length of the path traveled by light in vacuum during the time interval of 1/299,792,458 of a second

  4. Mass 1kg = mass of the platinum-iridium cylinder in Paris 1u = 1.6605 10-27kg ( unified atomic mass unit)

  5. Time 1s = 1/24*60*60 day=1/86400 day 1s = time required for 9,192,631,720 periods of radiation of the Cs-atom

  6. Vector Addition(head to tail) The 3 vectors Vi can be added by any order to form VR VR= (V1+ V2)+V3 VR= V1+(V2+V3)
