Students were creating graphs to illustrate the energy transformations that occur as a roller coaster moves along a track. The letters A-D on Graph 1 represent the position of a roller coaster as it moves along a track. The numbers 1-4 on Graph 2 were supposed to represent the energy of the roller coaster at positions A-D, but the students got their data mixed up. How should the bars in Graph 2 be ordered so that they match to the energy of the roller coaster as it moves from position A to B to C to D?
