I am trying to explain vectors to a 7th grade student and I am not sure that the concept of bound vectors is really useful. I'd rather just go straight to free vectors. For instance, I understand that addition is only defined for free vectors and not for bound vectors. Would you agree with this statement?
So I am not convinced that bound vectors are a useful concept. The only possible application I can imagine is when talking about "position vectors" but I 'd rather explain what they are without using the "bound vector" concept. In short, I am not sure what's the most reasonable and helpful way to introduce bound, position and free vectors (and in what order). The way I see it, both free and position vectors can be defined with only two numbers in the Cartesian plane, while bound vectors need four numbers. Given that the algebraic treatment of vectors in 2D uses two numbers, this further suggests that bound vectors do not provide any helpful insights to students.
Any thoughts on the subject and, in particular, is the statement "addition is not defined for bound vectors" correct? Obviously when I say "defined" I mean in the general case, for any two bound vectors.
