English: Line chart showing relation of average bowling ball speed as a function of travel time from foul line to headpin Chart is based on formula: Y mi/hr = 60ft * (1mi/5280ft) * (3600sec/hr) * (1/Xsec)
The USBC and World Bowling promulgate bowling ball specifications. USBC specifications include physical requirements for weight (≤16 pounds (7.3 kg)), diameter (8.500 inches (21.59 cm)—8.595 inches (21.83 cm)), surface hardness, surface roughness, hole drilling limitations (example: a single balance hole including the thumb hole for "two-handed" bowlers [3]), balance, plug limitations, and ...
The notch may be a hole completely through the bar or just a depression in it. The ball is pulled out of the notch by gravity when the device is slowly raised to an angle of about 20°, rolling onto the green at a repeatable velocity of 6.00 ft/s (1.83 m/s). [6] The distance travelled by the ball in feet is the 'speed' of the putting green. Six ...
Who cares if the ball was helped by a tailwind of 17-22-mph with 6,700 feet of elevation (though the temperature was in the low 50s)? That would be long enough to drive almost every par-5 in the U ...
