Simple harmonic motion create by prof lookang wee
I change interface only

The following is the applet created by ahmedelshfie (I just upload the jar file for him)

I would suggest that you should add the original URL when you post the modified simulations.
Ejs open source java applet Resonance simple harmonic motion SHM (http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=787.0) created by lookang (http://www.phy.ntnu.edu.tw/ntnujava/index.php?action=profile;u=14019)

thanks ahmedelshfie!
I understand you like the color scheme you have used, but can you share why you think the modified color scheme is more "beautiful" ? which Phet applet are you referencing from? Or is it your own design color?
Just curious.


I always thought the beauty of the applet is in the design of the various physics quantities that are commonly learnt in A level physics but no coherent applet to incorporate the physics ideas like "force, velocity, acceleration displacement, the 7 graphs etc" ;D I will re-look the applet and release a even better looking version soon!

Thanks for the g chat to understand your thoughts ;)

Thank you prof  ;D
This choose colour by my self and delete the field to add bars
For we have movement  ;) is beauty for simulation

In physics, simple harmonic motion (SHM) is the motion of a simple harmonic oscillator, a periodic motion that is neither driven nor damped.
A body in simple harmonic motion experiences a single force which is given by Hooke's law; that is, the force is directly proportional to the displacement x and points in the opposite direction.
The motion is periodic: the body oscillates about an equilibrium position in a sinusoidal pattern. Each oscillation is identical, and thus the period, frequency, and amplitude of the motion are constant
