Explore: Ground Reaction Force (biomechanics)

In physics, and in particular in biomechanics, the ground reaction force (GRF) is the force exerted by the ground on a body in contact with it. For example

ground, the ground will push back with equal force in the opposite direction. In certain fields of applied physics, such as biomechanics, this force by

Force platforms or force plates are measuring instruments that measure the ground reaction forces generated by a body standing on or moving across them
