A single mass attached to a spring, which is connected to a wall. An example of a simple linear oscillator. 

  • You can change mass, spring stiffness, and friction (damping).
  • You can drag the mass with your mouse to change the starting position.
  • Energy can be observed (potential, kinetic, total) by clicking the "show energy" checkbox. 
  • Graph tab shows any two variables including energy.
  • Time Graph tab shows any three variables against time.

Explanation of the math is available, along with open source code.
