Problem
A roller-coaster train moves through four consecutive segments: (1) a steep first descent, (2) the climb up a smaller second hill, (3) a vertical loop, and (4) a final rough braking zone bringing the train to rest. In one or two sentences, identify which single segment is likely to cause the greatest decrease in the train’s mechanical energy and justify your choice based on the physical processes occurring in that segment.
