Unit vectors
Definition
Unit vectors are vectors that have a magnitude of 1. They are used to represent direction and can be added or subtracted to other vectors.
Analogy
Think of unit vectors as arrows on a compass. Just like how the arrow always points in a specific direction (north, south, east, or west), unit vectors also have a fixed direction.

Vector Addition: Vector addition is the process of combining two or more vectors together to form a resultant vector. It involves adding their corresponding components.
