Vector trouble

jeepers101 · 2009-11-12 19:00:47

I'm having a bit of trouble comprehending some aspects of 3 dimensional vectors. I find stuff like the cross product, Moments of a force (M = r x F) and Velocity of a rotating body (v = w x r) very difficult to visualise. Does anybody know of any online resources that could help paint a clearer picture? Thanks in advance.

I always found the right-hand rule pretty useful for directions of the resultant vector in cross-product calculations
