Is there any proof for the Lagrangian:
$$L = T - U $$
And why L = T - U ?
Any help is much appreciated. Thank you.

Is there any physical explanation why L = T - U? Why we have the negative sign in the Lagrangian equation in U?What do you mean by proof? Lagrangian mechanics is a physics theory just as Newtonian mechanics. You don’t prove it, you test it experimentally.

This follows from the 2nd Newton Law +hypothesis that the constraints are ideal and holonomic +hypothesis that the forces are potentialIs there any proof for the Lagrangian:
