## Vectors in a plane

**Unit vectors and normalized vectors**

The green vector is the original vector.

The normal vector is blue and perpendicular to the original vector.

The unit vector has the magnitude 1 and the same direction as the original vector.

The normal vector is blue and perpendicular to the original vector.

The unit vector has the magnitude 1 and the same direction as the original vector.

The normal vector is the vector perpendicular to the original vector in counterclockwise direction.

The normal vector is denoted by a hat-like sign above the vectors letter.
