As the ball moves down the alley, the contact point will move, but the friction force will always be parallel to the line of contact between the bowling bowl and the surface. So, if we pick any fixed point S ...

Newton`s Laws 2.2
... An object at rest remains at rest and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force. Newton’s Second Law: The acceleration of an object depends on the mass of the object and the amount of force applied. ...
