WebEffect of friction on ball. Friction acts against the motion between the two contacting surfaces. Therefore, it both slows the speed of the ball and changes the speed of the spin. The change in spin can either be to increase or decrease/reverse the speed of the spin. Slide distance. The ball will slide and roll across the stringbed.
