A common activity that nearly any person ever could participate in is bowling. Whether you're a 35 year old professional, scoring 300 like its nothing or a 5 year old beginner using the bumpers, there still is one thing that always stays the same...physics. First of all, if you've ever stepped over the line while bowling, chances are you slipped and fell...why? The lane of the alley must have nearly no friction in order for the ball to maintain its initial speed, and to allow for better control of the ball and the application of spin. That brings us into spin. When a player apply spin to a ball the rotational inertia causes the direction of the ball to be altered based on the direction and amount of spin. Professionals look to make the ball travel in a near parabolic path in order to maximize the chance of getting a strike.
