Quizplus · Accepted Answer

At the highest point of the "around the world" maneuver, both gravity and the tension in the string provide the centripetal force necessary to keep the yo-yo moving in a circular path. Gravity acts downwards, and the tension in the string acts towards the center of the circle, both contributing to the centripetal acceleration.
