The roller coaster would only have potential energy at the point labeled “gravitational potential energy and kinetic energy.”

Answer 1

This is because at this point, the roller coaster is at its highest point and has the most potential energy stored in its height above the ground. As the roller coaster descends and gains speed, this potential energy is converted into kinetic energy as the coaster moves faster. At this point, the roller coaster has a combination of kinetic energy (energy of motion) and potential energy.
