The diagonal of the parallelogram represents the net force of the two given forces. The length of the diagonal represents the magnitude of the combined forces. The direction of the net force is along the diagonal and away from where the two forces are applied. When an object is changing its position with reference to another body, we say it is in motion. As with force, motion has a magnitude and a direction.
