Classical harmonic oscillator

The following options and plots are available:

• Slider to change the total energy of the system
• Sliders to modify the oscillating mass and spring rate
• You can also change the total energy by moving the black wall (left) with your mouse up and down
• Move the red part of the potential with your mouse left or right to change spring rate
• Plots for displacement, velocity, potential and kinetic energy
• Visualization of direction and strength of the effective force

After you did some changes, you may have to wait a few seconds to see the difference in the plotted curves properly.
