Hey everyone,
How indepth do I need to be memorizing formulas? Let's say, for instance, there is a moment of intertia problem, am I going to be expected to memorize the various moments (sphere, hollow sphere, rod, cylinder, etc.)?
Thanks,
Ari
Memorizing Formulas
Re: Memorizing Formulas
Yes, you'll need to know those. However, the recent exams have given you those on the front formula sheet.
Honestly, this test is all about memorizing formulas. Basic ones, you'll need to know the whole formula. Harder and more complicated formulas, you'll only need to know the general characteristics of the equation.
For example you'll only need to know the hydrogen energy levels go like 1/n^2.

If all they have to do is memorize formulas, isn't it funny how so many students still struggle with the test? There aren't that many formulas in physics.physguy wrote:Honestly, this test is all about memorizing formulas.

Thanks for the advice guys, I appreciate it.
Re: Memorizing Formulas
Depends on how much you memorize vs. derive. You only get 1.7 minutes (I think) a problem. Sure, you could start with Maxwell's equations and derive the rest of E&M from there. Not suggested though. But you're right in that a good portion of the test can't be answered from simple memorization.quizivex wrote:If all they have to do is memorize formulas, isn't it funny how so many students still struggle with the test?

That said, I used these to study:

Those and the practice tests were an excellent study combination. Much better I think than re-reading intro textbooks.

Re: Memorizing Formulas
Hmmm, very interesting...
I think I'll shoot them an email and ask for some flash cards, thanks a bunch!
