To find the unit vector of a vector, we divide each component by its magnitude. In this article, we will learn how to calculate unit vectors of vectors. We will learn about the formulas that we can use, and we will apply them to solve some practice problems.
Vector Practice. 1. Draw the components of each vector in the following diagrams. Then calculate the length of each component. 5. If I walk 20 miles North, then 15 miles East, then 10 miles at 35° South of East, What distance have I traveled? What is my displacement? If I travel the entire distance in 4 hours, then what is my average velocity?
