Two oppositely charged plates held at a fixed distance from each other make a field that doesn't really vary :o?

Also, I feel kind of bad for asking this question, but since I really don't understand it: What is a charge? I keep hearing/doing things with this thing "charge" and I actually don't get it.
Also, when I write out stuff like mass is 4.0 x 10^-6 kg, I write m = 4.0 x 10^-6 kg, but what's the symbol for charge?



EDIT: Oh, I guess the symbol for "charge" is Q or q. Except Q is "the charge that's affecting" and q is "the charge that is being affected"

EDIT2: I found an equation on my equations sheet that says
For a uniform E-field*: ΔV/d
I think the thing did fall after all...maybe, but the wording's weird? I'm going to try plugging things into this.
EDIT3: Except there isn't time nor acceleration..so did the thing even move ><
EDIT4: I don't think that works..assuming my free-body-diagram is fine I'm going to guess it's fine to find the force, then plug everything into F_e = |q|E
*What is an "E-field"?
