GROUND REACTION FORCE AND THE FORCE ON CENTER OF MASS

Force plate measurements pertain to standard investigations in biomechanics. Using force curves of drop jumps etc. The purpose is to analyze impulse, rise time or maximum of height. These forces are ground reaction forces, which are composed of the actions of the different parts of the human body. We usually imply a direct correlation to the force of Center of Mass (CM). But the human body is not rigid. We also need to take into account the case of dissipative forces
