Si base quantities and units

SI Base Quantities and Units


Metric si prefixes

Metric(SI) Prefixes


Chapter1 length

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


Si base quantities and units

Mass

1kg = mass of the platinum-iridium cylinder in Paris

1u = 1.6605 10-27kg ( unified atomic mass unit)


Si base quantities and units

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


Vector addition head to tail

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)


Vector addition by components

Vector addition(by components)

Components are projections along the axis

Find components by trigonometry
