[A] Standard of length, mass, and time: m, kg, s
[B] Building Blocks of Matter: atoms, (Nucleus + electrons), Quarks
[C] Density and atomic mass:
kg/m3
1 mole consists of Na of atoms
and weighs 1 atomic mass
[D] Dimensional analysis
Length [L]
Mass [M]
Time [T]
e.g. Velocity = [L][T]-1
Density = [M][L]-3
Force = [M][L][T]-2
[E] Unit conversion
1 mi/h = 1(mile/hour) = 1(1609 m)/(3600 s) = 0.5 m/s
[F] Significant figures
[G] Coordinate systems, Trigonometry, and Geometry
