It'll roll a lot further on concrete than grass because there is less resistance.
A ball would roll farther on concrete because....on grass,the grass would be to lumpy...concrete is just flat and hard.
I think it will roll further on concrete because the grass has dirt, and the dirt might stop the ball and the concrete is soft and without something that can stop the ball..
I think it's unanimous, golf balls roll farther on concrete because grass would slow the golf ball down.
