SUMMARY
The discussion focuses on how lifting objects, both light and heavy, affects a person's center of gravity. It is established that the body's center of gravity shifts continuously while lifting, requiring a counteracting force to maintain balance. When lifting heavier weights, the force exerted must equal the combined weight of the object and the individual to prevent falling. Newton's Third Law is applied, indicating that the ground must exert an equal force to support the individual and the lifted object.
