Yes and no. NASA calls it fuzz drag. The fuzz drag has a different effect as you described. But a pure smooth ball versus a non smooth one. The smooth one will have more drag. IE this is why a golf ball has dimples. Thanks for the information. I'm just trying to see how close this est. is. I have 240fps video. I calculated the average speed to bounce. Ball was just about on the line so I calculated at using 60ft travel distance. I just rounded the distance because of the downward distance ball has to take from strike to ground. That gives me an average. Maybe many unknowns to find max velocity? Thanks guys..
