A vector whose modulus is 1 is called a unit vector. What is the difference between two unit vectors? A vector whose module is 1 is called a unit vector. What is the difference between two unit vectors?

Get the concept straight.
A vector of 1 unit length.
Vector subtraction: The operation of finding the difference between two vectors is called vector subtraction.
A vector has length and direction, but a unit vector has no direction. So, in general, we find the difference between two vectors, not the difference between two unit vectors. It can only be a unit vector.
