▁human ▁lo com otion . ▁Typ ically , ▁a ▁human ' s ▁center ▁of ▁mass ▁is ▁detected ▁with ▁one ▁of ▁two ▁methods : ▁The ▁reaction ▁board ▁method ▁is ▁a ▁static ▁analysis ▁that ▁involves ▁the ▁person ▁lying ▁down ▁on ▁that ▁instrument , ▁and ▁use ▁of ▁their ▁static ▁equilibrium ▁equation ▁to ▁find ▁their ▁center ▁of ▁mass ; ▁the ▁segment ation ▁method ▁re lies ▁on ▁a ▁mathematical ▁solution ▁based ▁on ▁the ▁physical ▁principle ▁that ▁the ▁summ ation ▁of ▁the ▁tor ques ▁of ▁individual ▁body ▁sections , ▁relative ▁to ▁a ▁specified ▁axis , ▁must ▁equal ▁the ▁tor que ▁of ▁the ▁whole ▁system ▁that ▁constit utes ▁the ▁body , ▁measured ▁relative ▁to ▁the ▁same ▁axis . ▁ ▁See ▁also ▁▁▁ ▁B ary center ▁ ▁Bu oy ancy ▁ ▁Center ▁of ▁mass ▁( rel ativ istic ) ▁ ▁Center ▁of ▁per cussion ▁ ▁Center ▁of ▁pressure ▁( fl uid ▁mechan ics ) ▁ ▁Center ▁of ▁pressure ▁( ter rest rial ▁lo com otion ) ▁ ▁Cent roid ▁ ▁Circ um center ▁of ▁mass ▁ ▁Ex pected ▁value ▁ ▁Mass ▁point ▁geometry ▁ ▁Met acent ric ▁height ▁ ▁Roll ▁center ▁ ▁We ight ▁distribution ▁ ▁Notes ▁ ▁References ▁ ▁External ▁links ▁▁ ▁Mot ion ▁of ▁the ▁Center ▁of ▁Mass ▁shows ▁that ▁the ▁motion ▁of ▁the ▁center ▁of ▁mass ▁of ▁an ▁object ▁in ▁free ▁fall ▁is ▁the ▁same ▁as ▁the ▁motion ▁of ▁a ▁point ▁object . ▁ ▁The ▁Sol ar ▁System ' s ▁b ary center , ▁simulations ▁showing ▁the ▁effect ▁each ▁planet ▁cont ributes ▁to ▁the ▁Sol ar ▁System '
