Created by prof Hwang Modified by Ahmed

Original project EJS version of Vector addition (sum of two vectors)

The applet shows how vector was calculated.

1. Calculate X,Y components of vector ,,

2. If you un-check x-y mode:

The sum is equal to sum of parallel components of ,

**math_failure (math_image_error): \vec{B}**in the direction of ,

and the normal component of \vec{A},\vec{B} always cancel out with each other. i.e.

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

**Press the Alt key and the left mouse button to drag the applet off the browser and onto the desktop.**This work is licensed under a Creative Commons Attribution 2.5 Taiwan License
