Deriving Units
To be able to rearrange units into SI base units, *Always Change Units to SI Base Units e.g. cm à m*
𝐹(𝑁) = 𝑚 (𝑘𝑔) 𝑎 (𝑚𝑠 !" )
Multiples
Multiples Sub-multiples
10# kilo k 10!$ deci d

10 mega M 10 centi c
10& giga G 10!# milli m

1. Use a Formula to Relate Power
2. List the Units
3. Derive it into SI Base Units
𝑃 = 𝐹𝑣
𝑊 = 𝑁 × 𝑚𝑠 !$
𝑊 = 𝑘𝑔 𝑚𝑠 !" × 𝑚𝑠 !$
𝑊 = 𝑘𝑔 𝑚" 𝑠 !#
,1.3 Errors and Uncertainties
Rule:
𝑢𝑛𝑐𝑒𝑟𝑡𝑎𝑖𝑛𝑖𝑡𝑦 = 𝑝𝑒𝑟𝑐𝑒𝑛𝑡𝑎𝑔𝑒 𝑢𝑛𝑐𝑒𝑟𝑡𝑎𝑖𝑛𝑡𝑦 × 𝑚𝑒𝑎𝑠𝑢𝑟𝑒𝑑 𝑣𝑎𝑙𝑢𝑒
%𝑈$ + %𝑈" + ⋯ + %𝑈' = %𝑈()*
If a quantity is to a power, the power will be multiplied.

e.g. In a question of Area; 𝑅𝑎𝑑𝑖𝑢𝑠 = 3.0 ± 0.3 𝑚; 𝑈𝑛𝑐𝑒𝑟𝑡𝑎𝑖𝑛𝑡𝑦 𝑜𝑓 𝐴𝑟𝑒𝑎 = 2 × K#.+L × 100%
Significant Figures
use to minimum sig. figs. Based on the questions. (5.09 à 3 s.f.)

1.4 Scalars and Vectors
Scalars Vectors
Only Magnitude Magnitude + Direction
e.g. Speed, Power, Energy e.g. Velocity, Acceleration, Moments
