Quizplus · Accepted Answer

At the lowest point in a swing, the tension in the rope is greater than the child's weight because it must support the weight and provide the centripetal force necessary for circular motion. The child's acceleration is not downward at this point; instead, the acceleration is centripetal, directed towards the center of the circular path.
