EJS version of Vector addition (sum of two vectors)
« on: October 11, 2009, 03:59:59 pm »
This is EJS version of vector addition.

The applet shows how vector $vec{C}=vec{A}+vec{B}$ was calculated.
1. Calculate X,Y components of vector $vec{A},vec{B}$,
   $vec{C}_x=vec{A}_x+vec{B}_x$ and $vec{C}_y=vec{A}_y+vec{B}_y$
2. If you un-check x-y mode:
  The sum is equal to sum of parallel components of $vec{A},vec{B}$ in the direction of $vec{C}$,
   $vec{C}=vec{A}_p +vec{B}_p$
  and the normal component of $vec{A},vec{B}$ always cancel out with each other. i.e.
   $vec{A}_n+vec{B}_n=0$ or $vec{A}_n= -vec{B}_n$

You can select to operate in C=A+B , A=C-B or B=C-A mode.
