Never took physics. And it's WELL known in the car world that larger,(or slotted or drilled) rotors are nothing but bling.
CALIPERS do the work.
I'm afraid you're under some misconceptions.
Calipers apply the force, but rotors sink the heat. Both are involved in doing the work.
Larger rotors most definately help, because that's how the heat is removed from the brake system. They cool better and thus take longer to fade. This is a real, measureable, and well known effect in the real car world, the one where people drive on race tracks and try to go fast.
Put it this way, if you were right, all car rotors would be 6" in diameter to reduce unsprung weight.
Slotting/drilling is of some minimal value, but mostly affects initial wet performance and green fade.
Suggest you read the Carroll Smith "... to Win" series of books, you might learn something.
