Question

What is the unit vector in physics?

Answer 1

Unit Vector

1. Vectors are two-dimensional geometric entities with magnitude and direction.
2. A unit vector is one whose magnitude is equal to one. The "cap" symbol(^) is used to indicate unit vectors.
3. Unit vectors have a length of one.
4. It is commonly used to describe a vector's direction.
5. For example, a unit vector for vector A , $\overbrace{A}$is described as $\overbrace{A}=\frac{1}{\left|A\right|}\overrightarrow{A}$.
6. When we divide any vector by the magnitude of another vector, we get a unit vector. A direction vector can also be referred to as a unit vector.
