Well done. Two small things I have loved when I came across them: 5 Min Physics from UQ (PHYS1171) https://teaching.smp.uq.edu.au/fiveminutephysics/index.html

Well done. Two small things I have loved when I came across them: 5 Min Physics from UQ (PHYS1171) https://teaching.smp.uq.edu.au/fiveminutephysics/index.html#course=phys1171&lecture=L34_QuantifyingRadioactivity https://teaching.smp.uq.edu.au/fiveminutephysics/index.html#... Newton's cannon. Look at its beautifully simple source code - one short html + javascript file (I see your javascript code for orbital motion is similarly easy to follow.) https://physics.weber.edu/schroeder/html5/NewtonsCannon4.html https://physics.weber.edu/schroeder/html5/NewtonsCannon4.htm... Something I was going to further explore, if I had had to do more physics tutoring/teaching: https://www.geogebra.org/m/M4nBYbbG#material/fHHvnhjm https://www.geogebra.org/m/M4nBYbbG#material/fHHvnhjm
