Lagrange equations have the following three important advantages relative to the vector statement of Newton’s second law: (i) the Lagrange equations are written mostly in terms of point functions that sometimes allow significant simplification of the geometry of the system motion, (ii) the Lagrange equations do not nor-

As final result, all of them provide sets of equivalent equations, but their mathematical description differs with respect to their eligibility for computation and their ability to give insights into the In this case, the Euler-Lagrange equations p˙σ = Fσ say that the conjugate momentum pσ is conserved. Consider, for example, the motion of a particle of mass m near the surface of the earth. Let (x,y) be coordinates parallel to the surface and z the height. We then have T = 1 2m x˙2 + ˙y2 + ˙z2 (6.16) U = mgz (6.17) L = T −U = 1 2m x˙2 In this video we jave derived lagrange's equation of motion from D'Alemberts principle in classical mechanics. The R equation from the Euler-Lagrange system is simply: resulting in simple motion of the center of mass in a straight line at constant velocity. The relative motion is expressed in polar coordinates (r, θ): which does not depend upon θ, therefore an ignorable coordinate.

The equation of motion is a mathematical expression that describes the relationship between force and displacement (including speed and acceleration) in a structure. There are five main methods for its establishment, including Newton's second law, D'Alembert's principle, virtual displacement principle, Hamilton's principle, and Lagrange's equation. tion.

1) Lagrangian equations of motion of isolated particle(s) For an isolated non-relativistic particle, the Lagrangian is a function of position of the particle (q(t)), the velocity of the particle (q’ = ∂q/∂t) and time (t).
