Dear all I have come with a simple idea to generate the three laws of motion of Newton and would love to hear comments on its correctness. Assume equal point masses: the rule says ' the displacement of one point mass must be balanced by an equal and opposite displacement of another'. Since all masses are identical, the displacement of ten points one unit distance can be balanced by the displacement of one point ten times the distance.. or the 'sum of mass x displacement is zero everywhere'. That is the centre of mass of an isolated system never moves. Now differentiate wrt to time and you get conservation of momentum and diff again and get the conservation of force- ie action and reaction at any point and in any direction is equal. What is interesting about this is: 1- the centre of the whole universe never moves-accepted fact. 2-inertia have simple explanation. 3- ideas like the entanglement of particles across large distances can be accommodated- since we do not require particles to be at the same position.
