    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 consider relativistic Case, well u know that, energy is not just kinetic.... as it's mass will depend on velocity, then the time itself is relative, etc.

    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.

    ok dear it's not valid bcoz it is an non relativistic eqn like we didn't use any relativistic effects in eqn like mass and velocity .

    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 branch in Physics which deal with relativistic particles in special theory of relativity and general theory of relativity. Similarly there is a whole different study for Quantum mechanics of relativistic particle.

    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 experiment.and the beauty of this eqn is that it describes all things in good manner.

    if I replace potential by force then dimention will not match and it would be incorrect in physics and against of laws of physics so
