this is also a valid reason ..Because schrödiger's equation is itself derived from classical physics, like there we consider energy as K.E and P.E only, where as if we will consid...
if we will use these type of relations then sr equation would valid for relativistic particles.But we didn't use anything like that means it's for nonelastic particles.
When you deal with High speed ( relativistic particle) There Galilien transformation doesn't hold true, in those case, we have to apply Lorentz transformation. There is a seperate ...
so there would be potential not force. and remember Schroedinger never derived this eqn. One day he just wrote down this equation on the basis of his personal experience and experi...
