Question

What are cyclic Co-ordinates? Explain with suitable example.

Answer 1

Explanation:

If a particular coordinate does not appear in the Lagrangian, it is called 'Cyclic' or 'Ignorable' coordinate. A bead is free to slide along a frictionless hoop of radius R. The hoop rotates with constant angular speed around a vertical diameter. Find the equation of motion for the position of the bead.
