1) what is the physical meaning of L=0 .. from wiki ..i have found .."The Lagrangian, L, of a dynamical system is a function that summarizes the dynamics of the system." that means when L=0 ..the system has no dynamics ..as far as i know a free falling body has T=V in the midpoint ..that means it has no dynamics in the midpoint ..is not it ridiculous??

2)in the actual path time integral of lagrangian is minimum ..we know L=T-V ..if V becomes larger then the potential become larger that means if potential increases ..it needs less time to go one point to another..that is so peculiar to me .. it should be V-T ,or anything else.
