Spacial Velocity?

  1. Feb 6, 2009 #1
    I was doing some homework for GR when I came across the term "spacial velocity." What is its definition?

    It's in the context of finding the spacial velocity using the knowledge of the four-velocity U being U = (1+t^2,t^2,t√2,0) [I don't need help with the problem itself, I just need to know the definition in this context]

    Check out this post. They must be talking about the 3-vector I call [itex]\vec v[/itex]. (Note that I'm using units such that c=1).

    Oh yeah, and it's spelled "spatial". :biggrin:

    Hm, maybe not. Dictionary.com says that "spacial" is OK too.
