# Unit vector

Unit vectors are often notated the same way as normal vectors, but with a circumflex (e.g. $a-hat$ is the versor of a.)
Three common unit vectors used in component form are $i-hat$, $j-hat$ and $k-hat$, referring to the unit vectors for the x-, y- and z-axes respectively. They are commonly just notated as i, j and k.
They can be written as the following: $Components i,j and k$
