Pelk\u00e4st\u00e4\u00e4n 0,2 sekunnin reaktioaikana se ehtii noin 3,3 metri\u00e4, ja todellisessa liikenteess\u00e4 p\u00e4\u00e4t\u00f6ksentekokin vie aikaa, joten matka on viel\u00e4 pidempi. Siksi turvav\u00e4li on niin t\u00e4rke\u00e4.<\/p>\n<p>Reaktioaika liittyy my\u00f6s juoksukilpailuihin, joissa l\u00e4ht\u00f6 annetaan laukauksella (\u00e4\u00e4ni) eik\u00e4 valolla (n\u00e4k\u00f6). Reaktio \u00e4\u00e4neen on nimitt\u00e4in hieman nopeampi kuin reaktio valoon. Lis\u00e4ksi pikajuoksussa l\u00e4ht\u00f6 katsotaan varkasl\u00e4hd\u00f6ksi, jos juoksija liikahtaa alle 0,1 sekuntia l\u00e4ht\u00f6merkin j\u00e4lkeen. S\u00e4\u00e4nt\u00f6jen taustalla on ajatus, ett\u00e4 ihminen ei merkin kuultuaan pysty reagoimaan sit\u00e4 nopeammin.<\/p>\n<p>N\u00e4enn\u00e4isesti yksinkertainen leikki yhdist\u00e4\u00e4 upeasti ihmiskehon toiminnan (biologia) ja kappaleiden liikkeen lait (fysiikka), ja se on yll\u00e4tt\u00e4v\u00e4n syv\u00e4llinen tiedekoe.
