: your wrong a vector and a scalar are completely different.  5 is not a 
: vector called a scalar it is a scalar.  

   Well... actualy... if you REALLY wanted to get technical about it, 5 
   is a vector.  It's a 1D vector with a length of 5, and it's pointing in 
   the positive direction. ;)

: Look up in any physics book and a scalar is 
: defined as any given value.  5,10,3.116, any # is a scalar but a vector is 
: number WITH direction ie 5 at 13degress is a vector.

   I don't know TOO many physics applications that require 1D vectors, so 
   it would seem to me that most physics books would describe vectors of 2 
   or 3 components... which might confuse the actual definition of a vector 

   A Vector is simply a way of describing direction and magnitude.

   I have seen no definition of "Vectors" that says that they have to be 
   2D or 3D.
