When a ball first begins motion across a surface, it is obvious that it is a frictional force in the direction opposite the motion that causes the ball to roll instead of slide. When the ball begins to slow down, there must be a frictional force acting in the direction opposite the balls motion, but it would also appear that this force would make the ball roll faster. Since there can't be two frictional forces acting on the ball, what is it that causes the ball to be able to slow down and stop rolling at the same time?
Re: How does friction stop a ball from rotating while also slowing it down?
