    Lagrangian function L = T-V . where T and V are the kinetic energy and V is the potential energy of a system. Given a problem find an equation for T and V. and get the difference. In simple problems these can be obtained in terms of x,y z coordinates or in terms of r theta and phi. Google for Lagrangian of different systems or search for Lagrangian homework with solutions you will get the L for many systems. rbk

    The Lagarangian has no physical significance but it is the mathematical function devised to obtain the equations of motion

    Lagrangian function is basically represented by L and its nothing but difference between the kinetic energy and potential energy.
    L = T - V , where T is kinetic and V is potential energy.

    a function that describes the state of a dynamic system in terms of position coordinates and their time derivatives and that is equal to the difference between the potential energy and kinetic energy
