Learn how to determine the magnitude and direction of a vector. The magnitude of a vector is the length of the vector. The magnitude of a vector is obtained by taking the square root of the sum of the ...

In this video series, I will show you how to find the angle of a vector when given in component form or as a linear combination. To understand the direction of a vector, it is important to go back to ...

One of the most important topics taught at the start of introductory physics is the idea of vectors. Students really need proficiency with them if they are to use force and momentum. Just about every ...

Unit vectors have a magnitude of 1. The basic unit vectors are \(i = \left( \begin{array}{l}1\\ 0\\0\end{array} \right)\), \(j=\left(\begin{array}{l}0\\1\\0\end{array ...
