Chad McLean enlists the help of the Storm Technical Staff to explain RG, Differential, and the differences between Asymmetric balls and Symmetric Bowling Balls
OMG! Mind freakin' blown right now! I've been bowling almost 40 years and *never* had these terms explained so simply and clearly before...thank you! Now, I'm _definitely_ getting myself a Pro Motion for my birthday... 👍🤩
Careful....Ive got a feelin Storm might have a Jackyl LE on there hands with that ball. My friend got one, and litterly gets flair rings on HALF of the ball!! The most Ive ever seen is 8.
That was by far the best explanation of bowling ball physics I have ever seen! Well done...I may throw Motiv...but there is no denying how great the people at Storm are at what they do! I will be showing this in every clinic I teach at my Pro Shop! Thank you for this!
I really appreciated you folks at Storm for simplifying terms that have been gobbldygook to me and most bowlers for years. I guess my next bowling ball will be a Storm.
This is awesome and really well explained. It would also be incredibly helpful if alongside the explanations you guys added a chart displaying your balls that match up so that people that still have difficulty understanding this could get an idea of how this translates to say an Astrophysix moving a more than a Match Up Pearl for example.

We might want to add that once a Sym ball is drilled it is no longer symmetric, it will just not move as much as a Asym ball. Once holes are drilled you are changing the shape of the inner core. just and added note to those who have viewed this video
Well done with the demonstrations. Another way to "quantify" the force that is created by a moment arm, would be to suspend the ball from a fixed mechanical arm and measure the torque created at the pivot point, then moving the ball (lengthening or shortening the distance from the pivot-point, or changing ball weight with the same moment arm length) to show how that changes the amount of torque created around the axis of rotation (pivot-point), and why knowing where the PAP is, is critical in laying out a ball. The one thing I would have added, is the "right-hand rule" for torque. That would help many better understand what "drives" the ball to turn left-versus-right on the lane (because of the asymmetric weight block in relation to applied torque), or what is often referred to as the "ice skater effect". You could have then continued to show that's why higher rev-rates, create more break, even though the weight block and cover-stock are the same, by using a "low" versus "high" rotation rate applied by the air-gun.
Great explanation of the physical forces. Now explain why we should care. How does this relate to our specific ball choices? How will understanding these forces help us to knock more pins down?
nordattack Everyone should care because this type of knowledge makes it easier than ever to adjust between balls and know exactly what to go to when you first shoe up. Everything is put together in this series of articles for your convenience. Enjoy 👊 news.stormbowling.com/2017/03/17/knowing-your-roll/ news.stormbowling.com/2017/05/03/pin-to-distance/ news.stormbowling.com/2017/05/10/pin-up-vs-pin-down/ news.stormbowling.com/2017/06/11/psa-to-pap-distance/ news.stormbowling.com/2017/04/06/symmetric-vs-asymmetric-cores/
This is great! I have on question tho. For example, I have an emerald iq and a hyroad pearl. The hyroad has a higher rg than the emerald. But I can get way more hand into it than the emerald. Shouldn’t this be the other way around? Feels like I can crank the heck out of the hyroad but have to work extra hard to generate revs with the iq.
I appreciate the explanation and I understand what RG and diff do for ball motion. What confuses me is when you see the numbers on the site for a ball, you'll see for example 16 lb = 2.48 RG 15 lb = 2.49 RG 14 lb = 2.50 RG but it's got the same core in it. The cores are the same shape (for a particular model ball like the 900 global Reality for example) but I want to also assume they are the same mass too, but I suspect I am I wrong? For a lower RG core, more of the total mass would have to be closer to the center of the core (like the guy spinning with his arms in vs out), but if cores are poured in molds too, then it seems that the core material would distribute evenly throughout the mold theoretically making each core identical in mass distribution. But they must have slightly different weights and mass distributions to have different RG values. Are the molds slightly different shapes to distribute the mass in a particular way? How do you know which core is which when they all look and possibly weigh the same? and do you strategically put different mass/weight cores in the balls to make them either a 14, 15, or 16 lb ball or does coverstock amount control overall weight? How It's Made didn't go very deep into this. LOL!
So low rg high diff means high flare, high rg low differential is like a solid or hybrid weak symmetrical ball? Just very confused, I think a chart would help lots of people understand numbers better
Not exactly but close. Differential is flare potential. My interpretation to help me understand is this. A low differential of .02 will give me 2 inches of flare, so very little which in turns makes the hook motion on the backend very smooth. A differential of .06 will give me around 6 inches of flare, so at or near maximum amount which will give me more motion on the backend whether hard arc or flippy depending on the RG of the ball and coverstock surface. RG just determines where on the lane that ball starts transitioning. A low RG (2.46 - 2.49) ball will start transitioning earlier in the midlane (30 foot mark roughly) whereas the high RG (2.54 - 2.59) will start transitioning later towards the backend (40 - 42 foot mark). Medium RG balls (2.50 - 2.53) will start in the middle (35 foot mark). I hope this helps give a better understanding.
Damn it now I have to go by an asymmetrical ball now that I understand why I need one for my style of bowling. Wont be a hard buy either because the ball will get me in the money eventually and pay for itself.
If you cut the wheel in half it will give two identical pieces like symmetric. Still trying to comprehend because the wheel could also represent a symmetrical ball.
@@davidpena63 Rewatch the part where Chad spins the tire horizontally. That's the difference. The distribution of mass around the edge of the tire vs around the horizontal axis is very different.
