I have been thinking about Newton's Third law from the past three days and am not sure if i completely understand it.
I need some help answering/describing this situation i had been thinking about. Answers to this will tremendously help me in understanding the third law.
Say in an isolated system with no external forces exists two initially seperated, non-deforming objects A and B and the only force acting between the two objects is the force of gravity (i.e none of the other three fundamental forces are in play here). Initially both the objects are in rest. Due to gravity they will obviously collide after some time.
My question is, what will happen after collision? Isn't it impossible for the objects to stay collide and bounce away from each other? Won't the action reaction forces cancel each other out at collision in this situation?
please someone correctly explain in depth what will happen as time passes by in the above system, to me.
