# Angular momentum, velocity and center of mass

I have a small question.

Suppose I hold a given stick A of mass $$m_A$$ with attached a weight B with mass $$m_B$$ attached to it and that I start rotating it, eventually releasing it.

The general movement should be similar to an axe throw, with centre of mass roughly near the weight, depending on the ratio of the masses.

However, what would happen if during the rotation the stick hits an object and breaks near the point I was holding it?

Will the object immediately start to rotate around its center of mass, in our case near the weight?

What other effects will take place? I guess the rotational velocity is conserved, but what does this mean?

Is the center of the rotation different from the center of mass immediately after the break? is it moved towards the center of mass?
