When two forces of the same magnitude acting in opposite directions are applied on a CHAPTER 1
stationary object, the object remains at rest. Assuming the two opposing forces have different
magnitudes, the object will move in the direction of the larger force. The resultant force is the
single force that represents the vector sum of two or more forces acting on an object. Force and Motion II

between participant A and participant B. Observe also the magnitude of forces F and F
