The swinging of the ball is not like a ball on a massless string. Let's come up with a model of our free armswing: Think of it more like a ball on the end of a rod, so the model is a rigid body. Two scenarios: stationary and walking.Originally Posted by Aslan
- If you are simply swinging the ball while stationary, the only thing occurring is potential energy (height of starting position) becomes kinetic energy (speed at the bottom of the swing), which becomes potential energy at the top of the backswing. Assuming no losses and no muscle effort, there is no change in height. Just like an ideal pendulum.
- In the second scenario, walking introduces torque to the arm through the shoulder. This torque adds rotational acceleration of the arm about the center of mass (of the arm and ball). This rotational acceleration is in addition to the gravitational acceleration of the first scenario. So you get more speed, which becomes more potential energy at the top of the backswing. The key in this is that a torque is applied after the ball starts swinging and that this is a rigid body.

You're right Hammer. Sean Rash just called my cell phone...he told me he owes his entire professional career to Bowlversity...he'd have never made it to the PBA without it. Luckily Bowlversity created a time machine so it could go back and create the game. And good thing Al Gore invented the internet...or we'd have to drive to bowlversity to learn how to bowl.
Wow...the "right way" huh? Hey Hammer...help me out here...the "right way"...would the be left handed or right handed? Stroker, Tweener, or Cranker? what weight is the right weight for a ball? 3 step, 4 step, or 5 step? What is the correct target? Arrows? Dots? 3-point targeting? one-handed or two-handed?? Don't answer that last one!
Well...I sure hope you can help me out with the one "right way"...that'll really help me get a head start. Then I can go to bowlversity...and with a little practice...300 games every time!!! WooHooo!!!! Thanks Hammer. Brilliant.

Follow-up question Hammer...if theres only one "right way" (the opposite of my way I'm betting)...why do the pros all have such different approaches and styles. We need to get to the bottom of this so we can tell all the pros who are doing it wrong to stop being so pig headed and go to Bowlversity.![]()

To Aslan, no matter if you have a three step, four or five step approach it all boils down to doing your approach and swing a certain way to be consistent and to get better at bowling. You are determined to do it your way. So as long as you are happy doing what you are doing there is no sense in trying to tell you anything else.![]()
Aslan why are you so into conflict and being a sarcastic jerk in every thread you participate in?

Try the palm up delivery, giving the ball a end over end straight roll, it WORKS GREAT for me! Does away with the annoying kick to the left of 10 pin 100 percent of the time if done correctly! I can even use a Nano to pick it up with this method! Comfortable feel, and good on many other spare pick up where that HOOK at the end can destroy a great placement
Don't walk on Thin Ice!
Zax...funny!! Well played.
noeymc...Agreed. If Hoffman wants to throw stones and start fights...I'd prefer he PM me (as you did) so we can have it out rather than follow me from thread to thread to thread making rude little comments. But...what I "prefer"...I do not always "get"...so I'll just ignore the troll rather than feeding it.
