SUMMARY
The gravitational potential energy (GPE) of a 180 N child in a swing with 1.80 m long ropes is calculated relative to the child's lowest position when the ropes are horizontal. The relevant equation for this scenario is Kf + Ugf = Ki + Ugi, where K represents kinetic energy and U represents gravitational potential energy. The absence of velocity information at the horizontal position complicates the setup of the energy conservation equation, as potential energy can be determined solely from the child's weight and the length of the ropes.
