Why is there a need to find unit vector? If we are given a vector we can always find its direction.

A unit vector is a vector with a magnitude of 1 and is used to indicate direction in a specific coordinate system.
The direction of a vector is determined by the angle it makes with the positive x-axis in a specific coordinate system. This angle can be found using trigonometric functions such as sine and cosine.
To find a unit vector, divide the original vector by its magnitude. This will result in a vector with the same direction as the original, but with a magnitude of 1.
No, a unit vector by definition has a magnitude of 1, which is always a positive value.
Unit vectors are commonly used in physics and engineering to represent forces, velocities, and other physical quantities. They allow for easy calculation of quantities such as displacement, acceleration, and momentum.
