The correct statement according to the principles of energy conservation in a roller coaster scenario is:
Both potential and kinetic energy change, but total energy does not change.
In a roller coaster, as the coaster moves along the track, its potential energy (due to height) and kinetic energy (due to speed) transform into each other, but the total mechanical energy remains constant, assuming negligible friction and air resistance.
