what formulas

[armesty]

i know there are bunches of formulas for physics and chem to remember, but what are the main big ones if there are any? or important ones? plus do you need general knowledge of random scientists?

My advice would be to take formula sheets from the AP Chem and AP Physics B tests - hit all of those. The formulas that will probably score you the most physics points are the kinematics equations.

Knowledge of random scientists is helpful but not essential - there are at MOST two questions a test - so focusing on other stuff before memorizing who did what is probably the better way to go.

for physics, you can use many of the formulas for a whole range of topics, including momentum, magnetism, and nuclear energy. however, for things like kinematics, where many of the physics questions will be aimed, it is probably wise to not only learn the basics formulas, but the entire concept because kinematics is so important and can be a bit complicated. chemistry, there aren't so many formulas to memorize though you might try for electrochemistry and quantum numbers. mostly for chemistry you need to know your stuff because some of the titration and equilibrium problems require more than just a simple formula.
