Applets by Daniel Roth - Harmonic Oscillator

(c) 1999 by Daniel Roth, FiPS, Department of Physics, University of Kaiserslautern, Germany

Java Applet

A spring driven harmonic and damped oscillator is simulated. Please wait until spring and mass images are loaded...

If you use this Applet frequently or if you are having ideas for further Applets, please send me an email. Thank you!  

Instructions
 

m =	Mass of pendelum [ kg ]
D =	Strenght of Spring [ N/m ]
k =	Index of Newton friction (~ v)


Use the mouse to drag the mass to the desired position. Click onto "Start" to start the simulation. Different simulations can be compared by stopping the simulation, changing the desired values and restarting it without clicking onto "Reset". A click onto "Rest" completely resets the simulation and cleans the output.
To change m, D or k, type the desired value into the appropriate box and confirm with the Return key. Changes of m, D and k are also possible during a simulation.

The graph visible is the graph of position versus time. Sorry, that no labels are visible up to now. They will be inserted as soon as possible (which means it may take some time).

Notes

• The position of the mass is computed with numerical methods. Up to now the simple and less accurate Newton algorithm is used. It usually works fine, but in some special situations errors can and will occur (like in every numerical computation). If there is a need to implement a Runge Kutta 4 algorithm instead, please tell me.
