I just wanted to mention the preparation advice that already exists on the main site:
Main Preparation Advice Page
Please use this thread comment about what is written there.

Hi Grant,
In the preparating advice page on the main site you reference a page about various opinions, thoughts, and suggestions pertaining to the Physics GRE. Anyway, how did you determine what sites to link to on that "other opinions page".

Hi Imaginary_Friend,

Basically I looked everywhere I could think of to find relevant information about the Physcis GRE on the Web and those were the sites that I found. If anybody knows of any other relavant sites to link to then please post it in the forums and/or send me a private message (i.e. click the "pm" icon below).

Are you interested about Mechanics problems ? try this http://www.mechanics-book.net
Can you tell me (if you will visit the site and see sample problems) to what level is possible to be adessed? I mean high school , Physics faculty Mechanics faculty in USA? Thank you.

Hey mechanicsbook,

I liked your sample problems. I would say that those are at the undergraduate level. They are probably too advanced for for the Freshman introductory physics classes but probably medium difficulty homework problems for a Junior level classical mechancis course at most american universities. They are the kinds of problems kind you might see on a midterm exam in a class that uses Marion & Thronton.

They are probably a bit involved for the physics gre but if you simplified them a bit and also made them multiple-choice then they could be pretty representative of physics gre type mechanics problems.

can anyone confirm this,
the last question of the sample questions in mechanicsbook's post doesn't have a solution. i reckon;

a=g*k/(k+1)*{1+2*f*(H+h)/(H-h)}

.
In bref I can observe the following steps :
1)energetical consideration concerning the follow down of the body
2)the inellastic colision is as a matter of fact only in the vertical direction (normal direction )
3)Just before it the body has the mouvies , vertical-rectangular and circular around point " D " So there is near weight and tension a centrifugal force on it
Thank you , keep in touch,
