NodeWorks - Encyclopedia: Speed (184 words)
Speed (symbol: v) is the rate of motion, or equivalently the rate of change of position, expressed as distance d moved per unit of time t.
Speed is a scalar quantity with dimensions Length/Time; the equivalent vector quantity to speed is known as velocity.
Speed is measured in the same physical units of measurement as velocity, but does not contain the element of direction that velocity has.
Order of magnitude - Wikipedia, the free encyclopedia (942 words)
More precisely, the order of magnitude of a number can be defined in terms of the common logarithm, usually as the integer part of the logarithm, obtained by truncation.
