You are welcomed to check out [url=http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=1247.0]EJS version of Vector addition (sum of two vectors)[/url],too!
This java applets try to show : How to add two vector A and Binto vector C
C = A + B = B + A
How to play:
There are two methods to form a vector
1. Vector A/B originate from center of the window Left click anywhere inside the window to form vector A or B 2. Vector A/B originate from where you first click the button Drag and lift the left mouse button to form vector A or B Vector will move to center of the window.
The program will show you how to add two vector A and B into C
C = A + B
C = B+ A
C = A - B
C= -B + A
A - B can be transformed to A + (-B)
press reset button or right click the mouse button to reset.
Parameters are reset to default values.
select info checkbox to show more information.
X,Y components of each vector ... How to process more than two vectors :
= A + B + C + D
= (A + B) + (C+D)
= E+ F
E = A + B and F= C + D
Could you figure out how to process SUM = A + B + C ?3-D version
The following is a flash demo for the above java applet.
How to form a 3_D vector
Move the mouse with the window will establish a vector at X-Y plane. Left click the mouse, then drags it up/down to change the Z components. Then release the mouse button
When you form two vector A and B
Another vector C = A + B will show up.
Drag the right mouse button to change the viewing angle. Drag near the origin to change the its position.(displacement)
