Subject: Re: [Phys-l] Motion in 1D, vectors and vector components
I'm warming to this idea (more for lack of any other). I've never
been
particularly fond of writing vectors as
(v_x,v_y,v_z)
preferring unit vectors
V = v_x e_x + v_y e_y + v_z e_z
OTOH, most of my students come to me more familiar with the 1st
version
where the words "array element" are quite natural.
So I'm warming to this idea as well. I can start with the probably
more
familiar (v_x,v_y,v_z) and define an "array element", should be
familiar
to most of my students; then quickly segue to unit vector methods.

So I have.
Component vector -> which except at the very beginning I'll call a
"projection"
And an "array element"
