Momentum and energy in a collision

[ataskaita]

You are making the same mistake as many other people. You find something hard to understand in Classical Science and, instead of sorting it out classically, you think the answer lies in using buzz words and even more rarified stuff. If you don't get the basic stuff then you have no hope of getting any further.
Momentum is Conserved wherever we look in nature - Planets or Quarks. You will not have a clue (trust me) what a Quark is so why introduce it into the discussion?

For me it is ok with conservation and maybe i would like momentum, it is that just dv/dt is just maths and introducing new quantity by just explaining it as dv/dt or da/dt is just too unexplanatory. I would really apreciate simple life like explanation of momentum and not dv/dt...

This is no longer productive.

Both total energy and momentum are conserved. Not all energy is mechanical energy. Physics uses math.
