show that newton's third law of motion is connected in first law of motion
Answers
Newton's Fist and Second Law relate forces acting on a single system to conservation or changes of that system's momentum. It doesn't say anything about the nature of these forces, their origin; they could come "out of nowhere" and Laws 1 and 2 still hold.
The Third Law, however, indicates that all forces, or "actions", are just one side of an interaction. This view, that systems act on each other, by either attracting or repelling each other, still holds even in circumstances where other aspects of newtonian mechanics don't (i.e. relativistic or quantum mechanics). All forces observed since Newton's time until today are still modelized as being the results of the fundamental interactions.
One could say that the First Law describes the nature of momentum, the Third Law the nature of forces, and the Second Law the link between the two. The First and Third Law thus provide the setting where the Second Law is stated.
