Vector Addition
While we become students of physics and approach the job of adding vector quantities, we soon become aware of the fact in which the addition of two vector quantities along with magnitudes of 6 and 8 will not necessarily result in an answer of 14. The rules for adding vector quantities are various than the rules for adding two quantities arithmetically. Therefore, vectors along with magnitudes of 6 + 8 will not unavoidably sum to 14.
