Type question

Hey I am wondering, do moves used by the same type of pokemon inflict more damage?

For example would a flying type using a flying attack do more damage than a non flying type using a flying attack?

Yep.
It's called STAB (Same Type Attack Bonus)

Okay dude, you're really gonna have to start looking around more. This could have been asked in the BW Q&A thread tbh. I've had to lock about three of your threads now. :/ Please look around the forum and get an idea of where things are supposed to go.
