Re: Newton's 3rd law? was Re: inertial forces (definition)

I had to look up binormal in my Funk & Wagnalls. The definition sounds
like that for normal. What's the difference?

I think the normal lies in the plane which is tangent to the
trajectory and the binormal is perpendicular to that plane -
or is it the other way 'round? As I said, I don't use them.
I've never done much with general curvilinear motion.
