As a high speed rollercoaster slowly climbs to the top of a steep incline and then races down a hill and circles through loops, an energy transformation takes place. Which of the following statements is accurate? *
A-The kinetic energy is constantly equal to the potential energy.                                                                                     B-Some energy is destroyed.                                                     C-Some energy is gained.                                                    D-Some potential energy is transformed into kinetic energy and vice versa.
