Rotational Motion
... For a spinning ice skater, angular momentum is conserved when the skater pulls her arms closer to the center of rotation because it is an internal force that redistributes her mass with respect to the rotational axis. Only an external force with a lever arm can generate an external torque which can ...

... (b) A particle of mass m moves under a force F (x) = −cx3 , where c is a positive constant. Find the potential energy function. If the particle starts from rest at x = −a, what is the velocity when it reaches x = 0? Where with subsequent motion does it come to rest? 8. (a) Show that for an isolated ...

Vector coupling of angular momentum
... Many-Electron Atoms Hund’s rules: 1) The total spin angular momentum S should be maximized to the extent possible without violating the Pauli exclusion principle. 2) Insofar as rule 1 is not violated, L should also be maximized. 3) For atoms having subshells less than half full, J should be minimiz ...
