SUMMARY
This discussion clarifies the concepts of internal and external torque, specifically in the context of a person running towards a merry-go-round and grabbing its handles. Internal torque occurs when the forces acting on an object are generated from within the system, such as the rotational force exerted by the person on the merry-go-round. In contrast, external torque involves forces applied from outside the system, which are not present in this scenario as described by the professor.
