Web11. Actually, at least for a single point subjected to a friction force F = − γ v and other forces associated with a potential U ( t, x) there exists a Lagrangian: L = e t γ / m ( m 2 x ˙ 2 − U ( t, x)). The point is that this Lagrangian is not of the form T − U, nevertheless it gives rise to the correct equation of motion, the same ...
