The Lagrangian is indefinite with respect to addition of a constant to the scalar potential which cancels out when the derivatives in the Euler- ...
Why is the Lagrangian such a special quantity? : r/askscience - Reddit
NO!!! Only when the partial derivative wrt time of the lagrangian is zero! Equivalently the total time derivative of the hamiltonian is zero.
Different Lagrangians can lead to the same equations | Chegg.com
In particular, when we add to the Lagrangian the total time derivative of a function of the coordinates, the action changes only by boundary ...

The Euler-Lagrange equation for this Lagrangian is given by: d/dt (∂L/∂q̇) - ∂L/∂q = 0 Now, let's add the total time derivative term fqt to the Lagrangian.
In the Euler-Lagrange equation formulation, why is the time ... - Quora
In this sense, the Lagrangian is just some abstract function. After you define the appropriate Lagrangian function, you then let u(t) ...
So, we see that the Lagrangian function is specified up to a total time derivative by equation (26). This ambiguity is familiar, and we will not ...
