Ignorable coordinates
WebAn ignorable coordinate is a common term used in Hamiltonian mechanics to describe a cyclic coordinate. Conclusion A conservation law in physics states that an isolated … Webrewriting this in Cartesian coordinates. Since r2 = x2+y2 and cosφ= x/r. One finds 1−ex= r. Two special cases arise. For e= 0 one clearly has r = 1, i.e., a circle. For e= 1 one …

WebWhy are they called "cyclic" coordinates? In Lagrangian formalism, when ∂ L ∂ q = 0, the coordinate q is called cyclic and a corresponding conserved quantity exists. But why is it called cyclic? That link may hint at the answer by analogy with action-angle variables - the angle variable moves along a cycle in phase space.
