What forces are responsible for the circular motion of the center of mass of a gyroscope-like setup in precession?
Suppose we have a disk (of mass $M$) connected to a rod (of mass $m$) attached to a fixed pivot. (Note that initially I thought of the rod hanging off a rope, but I realized it would be better to ...

What exactly causes the velocity to change in conservation of angular momentum when an external force is applied?
Suppose an object is rotating in a circular motion, and we change increase its radius pulling it outwards in such a way that the net torque is always zero. In such a case, the angular momentum will be ...
