The single force that has the same effect on an object as all the forces acting on it together.
Revise: Resultant forcesRather than considering each force separately, they can be replaced by one resultant force with the same overall effect. Because force is a vector, a resultant must have both a magnitude, measured in newtons (N), and a direction.
