As the girl at the highest point of the swing begins to descend, her gravitational potential energy decreases while her kinetic energy increases. At the highest point, she has maximum potential energy (due to her height) and minimal kinetic energy (as her speed is momentarily zero). As she swings down, the potential energy is converted into kinetic energy, causing her speed to increase. Therefore, the overall mechanical energy of the system (assuming no significant air resistance or friction) remains constant, while energy shifts from potential to kinetic.
