Calculating the Modulus of a Vector
 
In this section, you will learn how to calculate the modulus of a vector. The modulus is a mathematical term for the length or the magnitude.
 
Zero vector and unit vectors

A vector with magnitude 0 is called the zero vector, written 0. A vector with magnitude 1 is called a unit vector.

Vectors are equal if they have the same magnitude and the same direction.

a = b zero vector

Inverse Vectors

The inverse of a vector is a vector of equal magnitude but in the opposite direction. The inverse of  is - or  and the inverse of a is -a.
