AP physics B :-)
ok. well i was making this for the exam. but got distracted. i have alot of it completed. to put it on a calc i use a special program which ill upload later. but so far im working on the data. the prog onthe calc reads text files.

feel free to use this. ill update the thread with the complete file after i get off work. i dont know if the AP exam for phys tomorrow is the state date or national.

Spoiler for Ap Phys:

i stopped at electricty. i think i got optics and circuits and general electricity left.

woah they do equations different where you come from...

speed: X/t
would be
speed = d/t

there are alot more

is that all of them?? i have a hp 50g how can i put these formula on there?

I am also an AP Physics student. Standard Physics classes use the variable 'd' for distance, while AP classes use 'x' for position. They are basically the same thing, but Physics at the college level often uses muliple forms of length measurements:
x = position
d = distance
s = distance (waves/optics)
b = base
y = height
h = height
L = length
