Prefixes used to designate multiples of a base unit. In general, when converting from base units (m, l, g, etc) or derived units (m2,m3, m/s, Hz, N, J, V, etc) to a multiple greater (kilo, mega, giga, or tera) than the base or derived unit- then divide by the factor. For example: 10m = 10/1000km = 1/100 km = .01km.
1: mass one (kg) m 2 : mass two (kg) d : distance between objects (m) Ƭ: Torque (Nm) F : Perpendicular Force (N) T: Period (s) f: Frequency (Hz) 1 and F 2 represent two different forces created by object 1 or 2 (N) d 1 and d 2 represent two different distances that object one or two are from the fulcrum or
