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

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.

Answer 1

The incorrect piece of information is:

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

This statement is wrong because at the point labeled "gravitational potential energy and kinetic energy," the roller coaster would have both forms of energy, not only kinetic energy. At this point, the roller coaster is moving (thus possessing kinetic energy) and is also elevated above the reference point (therefore having gravitational potential energy).
