When force is applied as seen in the previous laws, the object being affected by said force will apply an equal force in the opposite direction. This all happens taking into account that the two forces are on two different bodies or objects, that the objects' forces are the same size, without regarding the sizes of the objects, since the effects of the forces may differ if the bodies are of different masses, and the forces must happen at the same time, not in a following and evolving procedure-like process.
