What are the characteristics of vector addition? Addition of vectors satisfies two important properties. The commutative law, which states the order of addition doesn’t matter: a+b=b+a. The associative law, which states that the sum of three vectors does not depend on which pair of vectors is added first: (a+b)+c=a+(b+c). How do you use the Pythagorean […]
