The change in motion or acceleration of an object depends on its mass and the forces acting upon it. If an equal force acts on two objects of different mass then the more massive object will accelerate at a lower rate than the less massive object. If no other forces act on the objects then both will continue indefinitely.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
