What is bowling differential?

Differential is an indicator of a bowling ball’s track flare potential. Bowling balls with lower differentials are more stable, therefore generating less track flare potential. Bowling balls with higher differentials are unstable, therefore generating a much larger track flare potential.

How is math used in bowling?

Firstly, the most complex mathematical connection with bowling is calculating and measuring a perfect fit to customise your own bowling balls. This calculation involves the degree of flexibility your fingers have, the length of your span and the width of your finger tips.

What does RG and diff mean in bowling?

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 the science behind bowling?

According to website myteamexplore.com, the Science of Bowling can be explained in all three of Newton’s laws of motion – in one throw: “When we throw a ball down the alley, it continues to roll at the same speed until the friction from the floor, the pins and the wall behind the pins, slow it down and bring it to a …

What does RG mean in bowling ball?

radius of gyration
High RG. The USBC defines RG (radius of gyration) as: Measured in inches, radius of gyration is the distance from the axis of rotation at which the total mass of a body might be concentrated without changing its moment of inertia. Simply put, RG is when your ball begins to rev up.

What does pap mean on a bowling ball?

positive axis point
When the bowling ball rolls down the lane it revolves around its axis. There are two points at the ends of the axis: the negative (NAP) and the positive axis point (PAP).

What causes a bowling ball to hook?

The thumb must fall out of the ball first. Illegally, one can play with the weighting of the bowling ball, such as drilling the ball so that there is more side weight on the right side of the ball (for a right-hander,) which would cause the ball to pull from right to left, causing a hook.

How does scoring in bowling work?

The more pins you knock down, the more points you score. A single game consists of 10 “frames”, with each frame consisting of two chances to knock down ten pins (with the exception of the last frame). Each pin you knock down earns you a point, while you can also score extra points by hitting “strikes” or “spares”.

What does RG mean in a bowling ball?

Low RG vs. The USBC defines RG (radius of gyration) as: Measured in inches, radius of gyration is the distance from the axis of rotation at which the total mass of a body might be concentrated without changing its moment of inertia. Simply put, RG is when your ball begins to rev up.

What is RG value?

The Rg represents the root mean square distance of the molecule’s components from the mass center of the molecule. The single Rh and Rg numbers generated by a GPC/SEC analysis are the weight average values obtained from compiling the calculated values at each data slice.

What causes a bowling ball to curve?

The bowling ball consists of a hard outer shell with a weight block in the core (the inside of the bowling ball). The mass and shape of the weight block affects the spin of the bowling ball and how it curves as it rolls down the lane.

Can you use Windex on a bowling ball?

According to most bowlers who have used Windex as a bowling ball cleaner, it does wonders getting dirt and grime off the bowling ball. Windex can be a great option if your ball has been mucked up by more than just oil at the lanes, but there are better homemade bowling ball cleaning options out there for you.

What does differential mean on a bowling ball?

Higher differential results in higher flare and higher hook potential. Medium differential results in medium flare and medium hook potential. Lower differential results in lower flare and lower hook potential. Differential is the number used by bowling ball manufacturers to tell us track flare potential on a bowling ball.

What is the RG of a bowling ball?

The bowling ball differential RG is one key measurement engineers use to identify the difference of the RG of a given bowling ball’s “X-axis” (weight block vertical measurement) compared to the RG of the “Y” or “Z” axes (weight block horizontal measurements). Differential of RG is an indicator of a given ball’s flare potential.

What is the mass distribution of a bowling ball?

Within the core of any bowling ball exists measurements of mass distribution which are used to measure a bowling ball in motion on the lane-surface.

What is the differential ratio of a ball?

The differential ratio of the drilled ball is the most significant fac- tor that affects the shape of the ball’s motion. Differential ratio is defined as the intermedi- ate differential divided by the total differential.
