## What is the RG on a bowling ball?

Radius of Gyration (RG) – An account of the location of the mass inside a bowling ball. Rg tells us whether the ball has the mass toward the center of the ball (low rg), toward the cover of the ball (high rg) or somewhere in between (medium rg). High rg balls lope down the lane saving the energy until later.

## What is a high RG?

Within that shape, RG is determined by the location of the majority of the mass. The lower the RG number, the earlier the hook. High RG means the exact opposite: the higher the number, the more length the ball will create. When we see the RG number advertised on a ball box, they provide the low RG plane number.

## What is an RG value?

The Rg represents the root mean square distance of the molecule’s components from the mass center of the molecule. Similar to weight average molecular weight (Mw), these values are the most appropriate for characterizing the sample as a whole.

## What is the lowest RG bowling ball?

Low RG: 2.460” – 2.570”

## What does high flare mean in bowling?

The bowling ball flare potential is simply the maximum amount a bowling ball can migrate while traveling down the lane. Flare potential can be used as an indicator for which bowling balls are best suited, as example, to oily lane conditions (high flare) and which balls work best for dry lane conditions (low flare).

## What is RG and differential?

In short, the RG of a bowling ball is an account of the location of that mass inside the given bowling ball. Differential of RG is the difference between the maximum and minimum Radius of Gyration. RG-differential indicates the bowling ball’s track flare potential.

## What is an asymmetric bowling ball?

An asymmetrical core is a ball where the RG values of the Y and Z axes of the ball differ by more than 5%. It’s generally accepted that symmetrical drilled balls have a smooth, controllable motion. Asymmetrical balls can exhibit large amounts of track flare even with long pin-to-PAP (positive axis point) distances.

## What is intermediate differential bowling?

Intermediate differential – The difference in radius of gyration between the Y (high RG) and Z (intermediate RG) axes on the bowling ball. The higher the the intermediate differential the stronger a balls PSA.

## What does RG and B in RGB value of HTML color mean?

Also see palette. RGB ( red, green, and blue ) refers to a system for representing the colors to be used on a computer display. Red, green, and blue can be combined in various proportions to obtain any color in the visible spectrum. Levels of R, G, and B can each range from 0 to 100 percent of full intensity.

## What are the numbers on bowling balls?

Bowling balls have a RG (Radius of Gyration) converted to a scale of 1-10. RG numbers range from 2.460 to 2.800, but some companies have converted them to a 1-10 scale to help give the consumer a better frame of reference. Mass distribution numbers describe the distribution of mass in the bowling ball.

## What is PSA in bowling?

The preferred spin axis (PSA) on an asymmetrical ball is one of the most misunderstood topics surrounding bowling ball technology in today’s game. A majority of bowlers don’t realize how important it is and how much more the ball reaction can be fine-tuned when drilling an asymmetrical ball.

## What does top pin mean on a bowling ball?

The pin is a colored dot on the ball that signifies the position of the top of the core in the ball. With today’s high-tech bowling balls, the ball driller must know where the core is in the ball.
