| haha, that was pretty bad. i didn't even notice though. i dont feel ready at all, but i got a 4 on the last practice test i took. i think its just an intense curve |

| Haha, it's ok...same here. I just finished optics...just electrostatics/modern physics crap left 
Do you know if there's a lot of modern physics??? I can't memorize the time dilation/whatever bs...:S | |

| if you have 5 steps, just read that for modern
its seriously way better than pr's, and it's worth learning | |

| Ah..too bad then, I only got PR...
No red bulls for me though. I'm just gonna skip first 2 classes in the morning and hope my teachers don't notice...haha....
Could you list out the equations we need to know for modern physics? | |

| e=hf
Kmax=hf-(work function)
f0=(work function)/h
E[emitted photon]=deltaE
lamba=(hc)/(Ej-Ei)
lambda=h/p
E=mc^2
you need to know nuclear decay and about electron volts too.
I figured it out today in about half an hour. i wish i could somehow give you the 5 steps book though. it saved me days of time i spent trying to learn it from the pr. | |

| This should be helpful...I just realized I need to know this:
* isothermal process (at constant temperature, maintained with heat added or removed from a heat source or sink)
* isobaric process (at constant pressure)
* isometric / isochoric process (at constant volume)
* adiabatic process (no heat is added or removed from the working fluid)
o isentropic process, reversible adiabatic process (no heat is added or removed from the working fluid - and the entropy is constant)
* isenthalpic process (the enthalpy is constant) | |

| gosh...i would be happy if i got a 4...ouchh.....nearly everybody in my physics class told me they gave up on it and stopped studying for it, but i haven't gave up yet!! fortunately for me.....2 more hours until the exam....ahhhh!!!
how much do u think colleges care about the AP physics exam? | |

| I think you guys are underestimating the curve; 90% of the people taking it at my school don't know thermo, fluid, nuclear, or induction. Good luck to everyone and I hope this year's test is easy. | |
