I'm having trouble understanding electric potential. In my book it says "an electric force acts on a charge situated in an electric field." I understand this part. Then it goes on to say "If a charge is moved over a distance against this force, work is done against the electric force and the system gains electric potential energy." I don't understand what it means by "the system gains electric potential energy." What is "the system," and wouldn't it be more correct to say that "the charge gains electric potential energy" (since only the charge is being moved). I'm really confused.

Thanks for any help!

Edit: Looks like physics stackexchange doesn't like to be greeted (I had a "hi there" at the start of my post, which has now disappeared)
