Hello, PF! I had a quick question that I hoped maybe some of you could help me answer. The question is simple: Why is the cross product of two parallel vectors equal to the zero vector? I can see this easily mathematically through completing the cross product formula with two parallel vectors, but I wanted to know why this existed. How does this fit into the definition of a cross product? To my knowledge, in simple terms, the vector you get from a cross product operation results in a vector perpendicular to both the vectors. Anyway, if anyone could help explain this, feel free to in the thread. Thanks!
