because it has an orientation(a direction) it also helps later on with certain operations, but it is a vector because it has a length(1) and a direction(whatever that may be)
A unit vector is one which has a magnitude of 1 and is often indicated by putting a hat (or circumflex) on top of the vector symbol, for example: Unit Vector = â, â = 1.The quantity â is read as...
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector.it will be the unit vector in the direction of the vector times the magnitude of the vector.
