Moby Motion dives into physics again with this tutorial for the Molecular add-on. Following up on his introduction last December, this one is much more comprehensive.
I've made another physics simulation overview, this time for the Molecular addon script in Blender. Let me know what other comprehensive guides you'd like to see, ideally in the comments on YouTube. As always, let me know if you have any questions :)
This one is much more comprehensive, so it covers a few things not covered in the first: linking particles at birth, linking particles after they're made, how to emit particles rather than have them appear on frame 1.
The first tutorial was specifically how to make a ball pit, so this one is meant to introduce you to the script so you can make any scene you like :)
