The clocks aboard the airplanes were slightly faster than clocks on the ground. The effect is significant enough that the Global Positioning System's artificial satellites need to have their clocks corrected. [13] Additionally, time dilations due to height differences of less than one metre have been experimentally verified in the laboratory. [14]
That is, clocks at higher altitude tick faster than clocks on Earth's surface. This effect has been confirmed in many tests of general relativity, such as the Pound–Rebka experiment and Gravity Probe A. In the Hafele–Keating experiment, there was a slight increase in gravitational potential due to altitude that tended to speed the clocks ...
He is known for being an excellent athlete and a very fast runner, and it was said that he could run faster than a horse and that his shout could be heard over a distance of 5 miles. Military expeditions
The 200 metre time almost always yields a "faster" average speed than a 100-metre race time, since the initial slow speed at the start is spread out over the longer distance. [2] The current men's Olympic and world champion is Noah Lyles , while the current women's Olympic champion is Julien Alfred , and the world champion is Sha'Carri Richardson .
"People told me when you start at Hopkinton, it's all downhill, and you want to run faster than you should down those hills. So, I remembered their advice which was don't go out fast, take it easy ...
On July 2, 2010, Blackbird set the world's first certified record for going directly downwind, faster than the wind, using only power from the available wind during its run on El Mirage Dry Lake. The yacht achieved a dead downwind speed of about 2.8 times the speed of the wind.
Fourteen-year-old Vanessa Waite recently shattered the national record for the 200-meter run for 15- and 16-year-old girls at the AAU Junior Olympic Games in Greensboro, North Carolina.
The ability for blacks to run faster than whites was considered of such importance that a common proverb of the time went "What you don' hab in yo' haid, yuh got ter' hab in yo' feet". [14] Slave folksongs praised blacks for their running capabilities, comparing them to "a greasy streak o' lightning" or stating that one "ought to see that ...
