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 created by lookang

Embed a running copy of this simulation

Embed a running copy link(show simulation in a popuped window)
Full screen applet or Problem viewing java?Add http://www.phy.ntnu.edu.tw/ to exception site list
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
  • 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!

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" Grin I will re-look the applet and release a even better looking version soon!

Thanks for the g chat to understand your thoughts Wink

Thank you prof Grin
This choose colour by my self and delete the field to add bars
For we have movement Wink 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
