Title: EJS version of Vector addition (sum of two vectors)
Post by: ahmedelshfie on May 21, 2010, 07:26:01 pm
This following applet is EJS version of Vector addition (sum of two vectors)
Created by prof Hwang Modified by Ahmed
Original project EJS version of Vector addition (sum of two vectors) (http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=1247.0)

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.
