If a generalized coordinate qi is cyclic, the conjugate momentum pi=∂L∂˙qi is conserved.
Is the converse also true? To state more explicitly, if a conjugate momentum pi=∂L∂˙qi=C1
Assuming my little observation is correct what is an example (perhaps a physical one) of such a situation i.e., a conserved pi with a non-cyclic qi? I cannot immediately think of one.
