Proper velocity the traveling object. It equals the object's momentum p divided by its rest mass "m", and is made up of the space-like components of the object's four-vector velocity. William Shurcliff's monograph mentioned its early use in the Sears and Brehme text. Fraundorf has explored its pedagogical value while Ungar, Baylis and Hestenes have examined its relevance from group theory and geometric algebra perspectives. Proper velocity is sometimes referred to as celerity. Unlike the more familiar coordinate velocity v, proper velocity is synchrony-free (does not require synchronized clocks) and is useful for describing both super-relativistic and sub-relativistic motion. Like coordinate velocity
Our Velocity Our Velocity "Our Velocity" is the first single from "Our Earthly Pleasures", the second album from the band, Maxïmo Park. The single was released two weeks prior to the release of the album, on 19 March 2007. The music was written by Duncan Lloyd and the lyrics by Paul Smith of the band.
