Question

what is the unit vector?

Answer 1

A unit vector simply denotes the direction. If we have a vector 4i + 3j. I will use a 2D vector because it is easier to understand.

The magnitude of this vector is 5 units.

The unit vector will be 0.8i + 0.6j.

When you plot this unit vector on a graph paper. Along x axis, go 0.8 units. From this point, go up 0.6 units parallel to the y axis. The resultant will be 1 (the hypotenuse length).

If the value 5 is multiplies with this unit vector, it simply means that you produce the same effect of the vector 4i + 3j. with the vector 5 times 0.8i + 0.6j.

HLO MATE HERE IS UR ANSWER

❤. A vector of magnitude one unit is called a unit vector
