what will be the degree of freedom of a massless rod, moving freely in space with a particle which is constrained to move on it? What is meaning of massless rod?

$\begingroup$ massless rod is an ideal case,so massless rod should be treated as a 1D line or a rigid body with mass tending to zero or something with 0 degree of freedom(like string is treated in simple pendulum). $\endgroup$– BarryCommented Sep 11, 2019 at 14:40

$\begingroup$ A massless rod has zero degree of freedom, a particle that move on it has 1 degree of freedom $\endgroup$– EliCommented Sep 11, 2019 at 16:02
