Laplace’s equation in the polar coordinate system in details. Recall that Laplace’s equation in R2 in terms of the usual (i.e., Cartesian) (x,y) coordinate system is: @2u @x2 ¯ @2u @y2 ˘uxx ¯uyy ˘0. (1) The Cartesian coordinates can be represented by the polar coordinates as follows: (x ˘r cosµ; y ˘r sinµ.

when Fσ = ∂L ∂qσ = 0 . (6.15) We then say that L is cyclic in the coordinate qσ. 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.

2 r r ˙ φ ˙, because the Lagrangian doesn't contain any φ, thus derivative w.r.t. this should be zero. Well, I would express the kinetic energy (T) in terms of polar coordinates as well as the potential energy (V). Then the Lagrangian L=T-V. Assuming you are dealing with the position and speed of one object, cylindrical coordinates make sense only if part or all of them can be varied independently of the others.

For example, if the generalized coordinate in question is an angle φ, then lagrange’s equation in term of polar coordinates Conjugate momenta in polar coordinates"lagrange equation in polar coordinates""free particle in polar coordi Lagrange’s equation in term of spherical polar coordinates"lagrangian spherical coordinates"" spherical coordinates and find lagranges equations of motion in My doubt is, Is it legal to write the position vector in any vector basis say polar basis but having components which are functions of $x$, $y$ and then use the Lagrange equation? $$\vec r = f(x,y) \hat e_r + g(x,y) \hat e_\theta$$ As another example of a simple use of the Lagrangian formulation of Newtonian mechanics, we find the equations of motion of a particle in rotating polar coordinates, with a conservative "central" (radial) force acting on it. The frame is rotating with angular velocity ω 0. The (stationary) Cartesian coordinates are related to the rotating coordinates by: choose spherical polar coordinates. We label the i’th generalized coordinates with the symbol q i, and we let ˙q i represent the time derivative of q i. 4.2 Lagrange’s Equations in Generalized Coordinates Lagrange has shown that the form of Lagrange’s equations is invariant to the particular set of generalized coordinates chosen.
