help!!form any one study physics in english

hi Im a new collage studant and this is my first year in mechanical engineering but we studied physics in arabic including the symboles in school and when I went to the collage I was shaked beacause they changed the symboles to enghlish so if anyone could write the main physics symboles in english please heeeeeeeeeeeeeeeelp!!!

your post is way to general to get any real help. mechanical engineering covers a huge amount of physics, people could sit here all night giving the conventional symbols for equations/constans - so the best answer I can give you is to look at your texts and google.

the physics symbols i faced not just a normal english words most of them i dont have on my keyboard
take this symbols for example:

i dont want all symbols in physics i just want the main important symbols

v usually velocity or final velocity
u usually initial velocity
$$\lambda$$ is usually wavelength
c is speed of light
$$\pi$$ is always constant 3.14
$$\mu$$ can be heaps of different things depending on context

just a random selection of some commenly used symbols/constants
symbols are often used for several different things but you should be able to pick it up.

heres a comprehensive list of greek letters commonly used in maths and physics: http://en.wikipedia.org/wiki/Greek_letters_used_in_mathematics,_science,_and_engineering

thank you very much this was really helpful but i had just one question about the example i give do understand this equation and what this two symbols mean
the two symbols:http://www.4shared.com/photo/KTOk0Szh/2_online.html

what have you been studying? from memory epsilon can be permitivity but no not totally sure sorry. the symbols are epsilon and mu subscript o if that helps.

i didnt start studying yet(i have been in collage for just five days) but i know this about light and maxwell theory

sqrt(1/$$\mu$$*$$\epsilon$$) using the exact values will give the speed of light or any electromagnetic wave in in a vacuum. I would't worry about the symbols much this early on they will tell you what the symbols are when you come across them!

εo = 8.85 × 10-12 C2 / N·m2 is the permittivity of free space.
μ0 = 4π × 10-7 N/A2 is the permeability of free space.

Also, from your earlier post:

t is time
x, y, z are position coordinates in 3-dimensional space
f seems to be a general function of x & t or perhaps x,y,z & t
E is electric field, Ex is the x-component of electric field
ε and μ are the relative permittivity and relative permeability, respectively, of some material. The are both unitless.

thank you guys for your help
