When you are on a swing, and at the lowest point of your motion, is your apparent weight greater than, less than, or equal to your true weight? explain

In a circular motion there must be a centripetal force directed towards the center. At the bottom of the swing trajectory we can pretend you are in uniform circular motion, so the net force points up toward the center of the circle. Therefore, the swing must exert a larger upward force on you than the earth does in the downward direction. So your apparent weight is greater than your true weight.
