@brinnbelyea I teach Physics C, but yeah I think most of the fretting and lashing out was probably from Physics 1 teachers.
I'm definitely not looking forward to C's continuing evolution to look more and more like 1. This year's C FRQs were terrible. Just... not good questions because of the huge checklist of stuff that the writers had to jam into each one.
Original Doppler efffect animations I developed for a physics course last week: subsonic speed, mach 1, mach 1.5 and mach 2 visualizations of the formation of the sound barrier and the shock wave cone.

For my #APPhysics students I threw together a #Desmos simulation to illustrate field cancelation inside a spherical shell, a la Newton's "shell theorem".
For visual simplicity this is 2D only! It uses a ring and 1/r force rule as an *analogy* for a spherical shell in our 3D universe with a 1/r^2 force.
As you increase the number of particles in the ring, the results approach the theoretical limit as described by the shell theorem with a zero net field on the interior.
