The center of mass of the adult human body vertically is 10&nbsp;cm above the [[trochanter]] (the femur joins the hip),<ref>{{Cite journal |last=Palmer |first=Carroll E. |date=1944 |title=Studies of the Center of Gravity in the Human Body |url=https://www.jstor.org/stable/1125537 |journal=Child Development |volume=15 |issue=2/3 |pages=99–180 |doi=10.2307/1125537|jstor=1125537 }}</ref> with it in horizontally being located 1.4&nbsp;cm forward of the knee, and 1.0 behind the trochanter.<ref>{{Cite journal |last1=Woodhull |first1=A.

Typically, 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 segmentation method relies on a mathematical solution based on the [[physical law|physical principle]] that the [[summation]] of the [[torque]]s of individual body sections, [[relative motion|relative to]] a specified [[Axis of rotation|axis]], must equal the torque of the whole system that constitutes the body, measured relative to the same axis.{{sfn|Vint|2003|pp=1–11}}
