The gravitational - potential energy of an object is given by the formula $U = mgh$, where $m$ is the mass, $g$ is the acceleration due to gravity, and $h$ is the height. For a roller - coaster, the higher it is, the greater its potential energy. Among the given options, the top of the hill is the highest position.
