Since a few past days , I am struggling with finding an in depth atomic model of force exchange between colliding paricles (originally newtons third law) , because at this point of time i am unable to understand any least bit of quantum field theory or quantum electrodynamics , because its covered in a lot of math and i am not ready for that (i am currently in intermediate stages of high school ).
Because everything that commonly exchanges forces on earth is made of atoms , imagine two of them , with an atom A moving towards B and another atom B stationary.
Now there are are exactly three different combinations in which this collision can take place
- A and B are of equal masses.
- A is more massive than B.
- A is less massive than B.
# A and B are of equal masses #
During the developing of the model , i considered only the first case mentioned above .
The first thing "i feel so i want to state" is that, these atoms will not exert a considerable force on one another , until the moving atom is a specific distance from the stationary atom . Considering this as an assumption , as such a distance can be thought of anywhere in space , so dont think about it much. Coming back to the original scenario consider some position of B with respect to A ,such that there is no force acting on both atoms at this position but A's moving any smallest amount of displacement would result in a force applied on both the atoms , with the forces opposite in direction . So , let this displacement be X and the position of A after covering this X be P . At this point P , A must exert an force on B as well as should B apply the same force on A . If these both forces are exerted simultaneously , then newtons third law is correct , but if velocity of A decreases first by force of b and only after that A's accelerates B then , there would be an extra force being exerted on A as B starts to feel the force of "B" . But this must be incorrect for newtons third law to hold true . So I came up with this explanation for the simultaniety of this , as i could not find any on the internet , or maybe i could not understand any ;
The force that A , whether it may be an EM wave or something else , takes a time to emerge from its source , but velocity is continuous , i mean EM waves take some time Z to emerge from the nucleus but A will be still moving during this time . So as i already mentioned this point P , this point will be reached by the atom in the same time Z . So after A reaches p , the EM wave / waves will be released and they exactly apply a force on both atoms that it will create a velocity v in both the atoms in opposite directions , so that atom A who earlier had velocity v will come to an halt and B will start moving with velocity v .
## A is more massive than B ##
For explaining this i just needed the fact that bigger masses have stronger EM waves at every point in space , probably because of concentrated EM waves at every point in space. This would lead to the fact that as soon as atom A reaches the aforementioned point P there would be an great acceleration in atom B but little retardation in A.
##A is less massive than B.##
Well this one could be also explained by a similar reasoning like above.
SO is this model right ? if yes , please help me with the mathametics ? if not please suggest an alternative ?
