The image is a bar graph showing the total mechanical energy of a roller coaster car at different locations along the track, separated into kinetic and potential energy. The bar graph has a vertical axis labeled "Total mechanical energy (kJ)" and a horizontal axis labeled "Location." The graph shows four bars, labeled A, B, C, and D. Each bar is divided into two parts: a gray part representing potential energy and a black part representing kinetic energy. The graph shows that at location A, the roller coaster car has only potential energy, and as it progresses through locations B, C, and D, it gains kinetic energy and loses potential energy. The graph also shows that the total mechanical energy remains constant throughout the roller coaster's journey. The overall atmosphere is academic and informative, visualizing the physics of a roller coaster.

The correct statement according to the bar graph is:
Both potential and kinetic energy change, but total energy does not change.
This statement reflects the conservation of mechanical energy, which indicates that while potential and kinetic energy may convert into one another as the roller coaster moves along the track, the total mechanical energy remains constant throughout its journey.
