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)

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.

• Please feel free to post your ideas about how to use the simulation for better teaching and learning.
• Post questions to be asked to help students to think, to explore.
• Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!
