Lagrangian model
In physics, Lagrangian mechanics is a formulation of classical mechanics founded on the stationary-action principle (also known as the principle of least action). It was introduced by the Italian-French mathematician and astronomer Joseph-Louis Lagrange in his 1788 work, Mécanique analytique. Lagrangian … Skatīt vairāk Suppose there exists a bead sliding around on a wire, or a swinging simple pendulum, etc. If one tracks each of the massive objects (bead, pendulum bob, etc.) as a particle, calculation of the motion of the particle using Skatīt vairāk Newton's laws For simplicity, Newton's laws can be illustrated for one particle without much loss of generality (for a system of N particles, all of these equations apply to each particle in the system). The equation of motion for … Skatīt vairāk Dissipation (i.e. non-conservative systems) can also be treated with an effective Lagrangian formulated by a certain doubling of the degrees of freedom. In a more general formulation, the forces could be both conservative and viscous. If an appropriate … Skatīt vairāk • Astronomy portal • Canonical coordinates • Fundamental lemma of the calculus of variations • Functional derivative Skatīt vairāk Non-uniqueness The Lagrangian of a given system is not unique. A Lagrangian L can be multiplied by a nonzero constant a and shifted by an arbitrary constant b, and the new Lagrangian L' = aL + b will describe the same motion as … Skatīt vairāk The following examples apply Lagrange's equations of the second kind to mechanical problems. Conservative force A particle of mass m moves under the influence of a conservative force derived from the Skatīt vairāk The ideas in Lagrangian mechanics have numerous applications in other areas of physics, and can adopt generalized results from the calculus of variations.
