Document Summary
All bodies contain a unique point where if suspended motionless that body will remain balanced: this point is known as the center of gravity. For a rigid body, the center of gravity is also the same point about which a body"s mass is evenly distributed, i. e. the center of mass (com) For a human the com varies depending on: morphology, branch of biology that deals with the form and structure of organisms without consideration of function, the location of body segments. Since the weight of an object acts through the com, a static system of balanced torques can also be used to determine an objects com. If you weigh the person before they get on the reaction board, the only thing you don"t know is the distance to their com from their feet (fperson * dperson com) + mperson + mscale = 0.
