SUMMARY
The discussion focuses on creating a free body diagram (FBD) for an object in circular motion, specifically addressing the forces acting on the object. The primary forces identified are gravity and tension, with the equation for centripetal force given as T = mv²/r. The conversation clarifies that the net force acting on the object is the centripetal force, which is horizontal when the object is twirled in a horizontal circle. Additionally, the distinction between the forces acting on the object versus the string is emphasized.
