APPLETS BY DANIEL ROTH - LAW OF REFRACTION / TOTAL ...

A spring driven harmonic and damped oscillator is simulated. Please wait until spring and mass images are loaded... Instructions m = D = Strength of Spring 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.
