The record is 44.72 km/h (27.78 mph), measured between meter 60 and meter 80 of the 100 meters sprint at the 2009 World Championships in Athletics by speed. [4] [5] (Bolt's average speed over the course of this race was 37.578 km/h or 23.35 mph.) [6] Compared to quadrupedal animals, humans are exceptionally capable of endurance, but incapable of great speed. [7]
The foot per second (plural feet per second) is a unit of both speed (scalar) and velocity (vector quantity, which includes direction). [1] It expresses the distance in feet (ft) traveled or displaced, divided by the time in seconds (s). [2] The corresponding unit in the International System of Units (SI) is the meter per second.
The Australian tiger beetle, Rivacindela hudsoni, is one of the fastest running insects in the world relative to body size, which has been recorded at 6.8 km/h (4.2 mph) or 171 body lengths per second. It can fly at 43 km/h (27 mph). Paratarsotomus macropalpis: 22 cm/s (8.7 in/s) 0.8 km/h (0.5 mph) 0.7 mm long mite endemic to Southern ...
The world record in the 100-meter dash in 1924 was 10.4 seconds, while in 1948, (the first use of starting blocks) was 10.2 seconds, and was 10.1 seconds in 1956. The constant drive for faster athletes with better technology has brought man from 10.4 seconds to 9.58 seconds in less than 100 years.
Johnson has run 200 m in under 19.80 seconds six times, and he has run the distance in less than 20 seconds twenty-three times. He holds nine of the top 50 200 m performances of all time. [22] Johnson has run twenty-two 400 m races in under 44 seconds; he holds twenty-two of the top 50 and four of the top ten 400 m performances of all time. [22]
The Ethiopian runner broke the 12-year old mark, finishing the 26.2-mile race in 2 hours, 4 minutes and 58 seconds on Sunday — eight seconds faster than Geoffrey Mutai in 2011.
The fastest possible speed at which energy or information can travel, according to special relativity, is the speed of light in vacuum c = 299 792 458 metres per second (approximately 1 079 000 000 km/h or 671 000 000 mph).
In terms of judging a person's speed, the best method of timing is through lasers which start and stop the times when passed through. A laser start (from a stationary position) is more accurate for measuring pure speed as it does not register a runner's reaction time, however, this method of timing a 40-yard dash can affect the accuracy by as much as 0.5 seconds with the manual stopwatch method.
