A unit vector is a vector with a magnitude of 1. It’s typically used to characterize the course of a vector. To search out the unit vector of a vector, we merely divide the vector by its magnitude.
Unit vectors are necessary in lots of functions, corresponding to physics and engineering. In physics, unit vectors are used to characterize the course of forces, velocities, and accelerations. In engineering, unit vectors are used to characterize the course of forces, moments, and stresses.
