i think the princeton review has a good equation list (for physics). i believe it is at the end of the physics section...
a lot of equations are recurring, and some of the ones that you should know, off the top of my head are:
The Big Five-- projectile motion and such (making sure to break values up into their x and y components).
E=hf
v=lamda x f
PV=nRT
f (flow rate) = Av
F=ma
wg for inclined planes= mg (cos theda)
W=Fd (cos theda) or =FV or =change in KE
i mean, these equations are just ENDLESS!
KE= 1/2 mv^2
PE=mgh
PE= 1/2 kx^2 for springs
there ar etoo many to write!
i would try to track down that TPR list. it is solid.
