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
The Velocity of Gary The Velocity of Gary The Velocity of Gary, also known as The Velocity of Gary* *(Not His Real Name), is a 1999 American dramatic comedy film directed by Dan Ireland and written by James Still, based on his homonymous play. It stars Thomas Jane in the title role, along with Salma Hayek and Vincent D'Onofrio. Gary (not his real name, which is never revealed) is a hustler walking through the streets of New York City, looking for business.
