This image of a roller coaster is designed to show important information about potential and kinetic energy. One of these pieces of information is incorrect. Which information is wrong, and why?

a
The spot marked “maximum gravitational potential energy” should be on the lowest point of the roller coaster, at the far left side on the bottom.
b
The spot with the “maximum kinetic energy” should be on the lowest point of the roller coaster, at the far left side on the bottom.
c
The roller coaster would only have kinetic energy at the point labeled “gravitational potential energy and kinetic energy.”
d
The roller coaster would only have potential energy at the point labeled “gravitational potential energy and kinetic energy.”

The incorrect information is option d: "The roller coaster would only have potential energy at the point labeled 'gravitational potential energy and kinetic energy.'" This is incorrect because at that point, the roller coaster has both potential and kinetic energy. It has potential energy due to its height and gravitational pull, and kinetic energy due to its motion.
