Chart is based on formula: Y mi/hr = 60ft * (1mi/5280ft) * (3600sec/hr) * (1/Xsec) = (40.909 / X) mi/hr where Y = average ball speed (mi/hr) and X = travel time (sec) Technical note: most SVG code was automatically generated by the "Line charts" spreadsheet linked at User:RCraig09/Excel to XML for SVG. Minor additions and adjustments were made ...

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 ...
For most of baseball's history, there were no commonplace methods to quantify how hard-hit a batted ball was — the only aspect of the ball's speed being tracked was how fast the pitcher threw it, measured using various evolutions of radar guns. In 2015, MLB introduced Statcast technology to all 30 of its ballparks, in part to track exit velocity.

During the first 0.05 s the ball drops one unit of distance (about 12 mm), by 0.10 s it has dropped at total of 4 units, by 0.15 s 9 units, and so on. Near the surface of the Earth, the acceleration due to gravity g = 9.807 m/s 2 ( metres per second squared , which might be thought of as "metres per second, per second"; or 32.18 ft/s 2 as "feet ...
The two primary forms are throwing for distance and throwing at a given target or range. The four most prominent throwing for distance sports are in track and field: shot put, discus, javelin, and the hammer throw. Target-based sports have two main genres: bowling and darts, each of which have a great number of variations.
