1. The problem statement, all variables and given/known data

what point and about what kind of axis can we conserve angular momentum?can we conserve it about a point moving in circular motion?
2. Relevant equations

3. The attempt at a solution
its just a understanding based question to apply to problems

Conservation of angular momentum is a phenomenon and not a quantity which may have point, direction etc.
I don't understand your next question. But I think this may help you-You don't need to conserve the momentum, rather it's in nature that the momentum will always be conserved provided the fact that no external torque is given.

i wanted to say for example there is rod standing with base on ground.u hit it say with some ball or anything it will begin to rotate.on ball+rod system about what point (centre of mass or point on base on ground or any other point) can i conserve angular momentum and apply equations.in which case i would be wrong to conserve it and why?
