Ah right don't worry then, but it's pressure, gas density and average square of gas particles' velocities respectively. It will only make sense if a teacher goes through it with you really, or if you're really good at making big logical leaps when reading a derivation
People have asked for a thread so here we go! We can discuss exam questions or general content if you need help.
I won't be revising for a while but if I can help, I'll try, means less revision for me in the summer if I help people earlier on (or if people explain to me!)
I think we've pretty much finished G484 except SHM maybe? I'll update this post with revision stuff.
We've done the first but not the second and I do specifically remember him saying "you don't need to know this I just think its interesting and helps you understand it more"
Has anyone's teacher gone over the actual mathematical proof that p=(1/3)(rho)c^2, or E=(3/2)kT? Ours has -- not 100% certain it's required for Newtonian as it's not in the spec.
In case you want notes on proof for the E=(3/2)kT equation, I have them on my physics notebook. My board is obsessed with proving equations. I'll upload the proof tomorrow if you want, it's really simple.
See I love space and astrophysics... But it's so dull. Medical physics gonna be dull. Electricity gonna be dull. All ****
Ohh we haven't done that yet. The nuclear physics will be interesting, the fundamental particles chapter would be better if it was more than just learning them all
