I disagree with the quibble about the term, as well as about the definition.
Since youth, I have heard the term "escape velocity" and am unaware of problems with it. Velocity is a vector, of course: the combination of speed and direction. We don't need to scold our readers if they use [[speed]] and [[velocity]] interchangeably.
Also, I'm not sure if an object traveling at this speed will always follow a parabola. It would depend on the direction with respect to the planet's center. Let's try to tighten this up. --[[User:Ed Poor|Ed Poor]] <sup>[[User talk:Ed Poor|Talk]]</sup> 10:50, 1 December 2009 (EST)
