I'm not sure of my answer kasi dun sa sentence constuction mo, friction ba lesson niyo? anyways.. here's my answer. The friction of the floor can affect how fast or slow the ball will roll. Friction is the relative motion of two solid objects which presses the surfaces together as well as the roughness or smoothness of the floor. Then if the surface of the floor is smooth, the ball will roll fast but if the surface is rough, it would stop easily or move slower than the ball in the smooth floor.
