For example, if the rotation occurs due to the torque exerted by some known object, putting that object into the system removes it from the surroundings. Thus that object is no longer considered to exert a torque on the system (a system cannot exert a torque on itself). The object transfers angular momentum to other parts of the system. This is a good method for dealing with the situations. | For example, if the rotation occurs due to the torque exerted by some known object, putting that object into the system removes it from the surroundings.

If all the objects are in the system, there are no external torques hence, the initial and final angular momentum of the system are the same, | If all the objects are in the system, there are no external torques hence, the initial and final angular momentum of the system are the same, |
