Question

what is use of unit vector​

Answer 1

Explanation:

Vector quantities have a direction and a magnitude. ... These unit vectors are commonly used to indicate direction, with a scalar coefficient providing the magnitude. A vector decomposition can then be written as a sum of unit vectors and scalar coefficients.

Answer 2

Answer:

A unit vector is any vector that has a magnitude of one and could be pointing in any direction. such vector are usually used to specify direction and therefore they do not have any dimensions or unit like other vector (e.g. m/s Fotheringhay velocity or m/s (sq) for acceleration )
