It is understood to refer to the second-order diﬁerential equation satisﬂed by x, and not the actual equation for x as a function of t, namely x(t) = LAGRANGE’S AND HAMILTON’S EQUATIONS 2.1 Lagrangian for unconstrained systems For a collection of particles with conservative forces described by a potential, we have in inertial cartesian coordinates m¨x i= F i: The left hand side of this equation is determined by the kinetic energy func-tion as the time derivative of the momentum p i = @T=@x_ Derivation of the Euler-Lagrange Equation (click to see more) First of all, we need to think about what the Lagrangian and the action are actually functions of.

Concluding Remarks 15 References 15 1. Introduction In introductory physics classes students obtain the equations of motion of free particles through the judicious application of Newton’s Laws, which agree with em-pirical evidence; that is, the derivation of such equations relies upon We use cookies to distinguish you from other users and to provide you with a better experience on our websites.

Warning 2 Y satisfying the Euler-Lagrange equation is a necessary, but not sufficient, condition for I(Y) to be an extremum. In other words, a function Y(x) may satisfy the Euler-Lagrange equation even when I(Y) is not an extremum. Lagrange's equations are fundamental relations in Lagrangian mechanics given by.
