Damped Harmonic Oscillator Energy Graphs

So, I got distracted from curriculum development, so here are some graphs I was curious about. They were made on my phone using desmos.

Energy vs Time, including total, kinetic, potential, and thermal.

Energy vs Distance Traveled

Mechanical Energy vs Position

Energy vs Position, including total, kinetic, potential, and thermal.

Now With less Damping

Now Critically Damped (this one is not released from rest)

And of course, no damping
