The correct statement according to the principles of energy transfer in a roller coaster system is:
**The roller coaster’s kinetic and potential energy change from location to the next, but its total energy remains the same.**
In a closed system, energy is conserved. As the roller coaster moves through different heights and speeds, potential energy is converted to kinetic energy and vice versa, but the total mechanical energy remains constant (ignoring friction and air resistance).
